fix(BToggle)! Remove redundant attribute cleanup & update docs for accessibility attributes on show/hide components #2918

dwgray · 2025-11-19T00:33:53Z

Describe the PR

Overview

This PR refactors ARIA attribute management for show/hide components to eliminate redundancy and improve maintainability while preserving all existing functionality. Fixes #2910

In addition:

I've updated the accessibility documentation for all related components
I've Added an document to the new architecture directory to describe how this system works
I've updated copilot-instructions.md with some information about how to write and reference sample code

Problem Statement

The previous implementation had overlapping responsibilities between the v-b-toggle directive and the useShowHide composable:

Directive was removing aria-expanded, aria-controls, and CSS classes on unmount
Composable was also managing aria-expanded and classes through its registration system
This duplication created confusion about which layer owned which attributes
Documentation didn't clearly explain the registration-based system

Solution

Clear Separation of Responsibilities

v-b-toggle Directive - Manages static relationship attributes:

✅ Sets aria-controls (knows target IDs from binding)
✅ Removes aria-controls on unmount
✅ Registers trigger with component
❌ No longer manages aria-expanded or classes

useShowHide Composable - Manages dynamic state attributes (for registered triggers):

✅ Sets aria-expanded based on visibility state
✅ Manages collapsed/not-collapsed CSS classes
✅ Updates all registered triggers when modelValue changes
✅ Cleans up attributes on unregister

Why Split This Way?

The division is based on static vs dynamic characteristics:

aria-controls = Static
- Lists which elements this trigger controls
- Set once, doesn't change with visibility state
- Only the directive has access to target IDs from binding
aria-expanded + classes = Dynamic
- Changes every time visibility changes
- Must update ALL registered triggers (not just the one clicked)
- Composable watches modelValue and handles centrally

Code Changes

1. BToggle Directive Cleanup

File: packages/bootstrap-vue-next/src/directives/BToggle/index.ts

Change: Updated handleUnmount to only remove aria-controls

// Before
const handleUnmount = (el, binding, vnode) => {
  // ... unregister logic ...
  el.removeAttribute('aria-controls')
  el.removeAttribute('aria-expanded') // ❌ Removed
  el.classList.remove('collapsed') // ❌ Removed
  el.classList.remove('not-collapsed') // ❌ Removed
  delete (el as HTMLElement).dataset.bvtoggle
}

// After
const handleUnmount = (el, binding, vnode) => {
  targets.forEach((targetId) => {
    const showHide = showHideMap?.value.get(targetId)
    if (!showHide) return
    toValue(showHide).unregisterTrigger('click', el, true) // ✅ clean=true
  })

  el.removeAttribute('aria-controls') // ✅ Only remove what directive manages
  delete (el as HTMLElement).dataset.bvtoggle
}

Impact: The composable's unregisterTrigger(clean=true) now handles cleanup of aria-expanded and classes, eliminating duplication.

How the System Works

The Registration System

ARIA management is opt-in through trigger registration:

Registered triggers (get automatic ARIA management):

Using v-b-toggle directive → automatic registration
All registered triggers update when visibility changes (regardless of source)

Unregistered triggers (manual ARIA management required):

No v-b-toggle directive
Must manually manage aria-controls, aria-expanded, and classes

Data Flow Example

// User clicks button with v-b-toggle
↓
// Directive registered this button on mount
↓
// Click event calls component's toggle()
↓
// Component's modelValue updates
↓
// useShowHide watch() fires
↓
watch(modelValue, () => {
  triggerRegistry.forEach((t) => {
    checkVisibility(t.el) // Updates aria-expanded + classes
  })
})
↓
// ALL registered triggers now reflect current state

Key Insight: The watch mechanism ensures ALL registered triggers update, regardless of HOW visibility changed (directive click, v-model, slot function, etc.)

Usage Patterns

Pattern 1: Automatic (Recommended)

<BButton v-b-toggle.my-collapse>Toggle</BButton>
<BCollapse id="my-collapse">
  <BCard>Content</BCard>
</BCollapse>

✅ Full automatic ARIA management

Pattern 2: Automatic + Programmatic Control

<BButton v-b-toggle.my-collapse>Toggle</BButton>
<BButton @click="visible = false">Close</BButton>

<BCollapse id="my-collapse" v-model="visible">
  <BCard>Content</BCard>
</BCollapse>

<script setup>
import {ref} from 'vue'
const visible = ref(false)
</script>

✅ First button gets automatic ARIA (registered)
✅ First button updates when second button closes collapse
❌ Second button has no ARIA (not registered)

Pattern 3: Manual ARIA Management

<BButton
  aria-controls="my-collapse"
  :aria-expanded="visible ? 'true' : 'false'"
  :class="visible ? 'not-collapsed' : 'collapsed'"
  @click="toggle"
>
  Toggle
</BButton>

<BCollapse id="my-collapse" v-model="visible">
  <BCard>Content</BCard>
</BCollapse>

<script setup>
import {ref} from 'vue'
const visible = ref(false)
const toggle = () => {
  visible.value = !visible.value
}
</script>

✅ Full manual control
⚠️ Developer responsible for keeping attributes in sync

Testing

All existing tests pass with no changes required:

✅ 1643 tests passed
✅ Build successful
✅ Linting passed

Test coverage includes:

v-b-toggle directive behavior
useShowHide registration/unregistration
Multiple triggers per component
Rapid mount/unmount cycles
v-model integration

Breaking Changes

None. This is purely an internal refactor:

External API unchanged
All usage patterns continue to work
No changes required in user code
Existing tests pass without modification

Walkthrough

Adds a comprehensive ARIA visibility architecture and docs, updates component accessibility docs to reference a centralized ARIA trigger-registration system, adds three demo Vue SFCs, and changes the v-b-toggle unmount cleanup to delegate aria-expanded and visual-class cleanup to the show/hide composable.

Changes

Cohort / File(s)	Change Summary
Repo-wide contributor/CI guidance `\.github/copilot-instructions.md`	Expanded contributor and documentation guidance: setup, build/test steps, servers, architecture, examples, testing, timing, and conventions.
Component docs — accessibility updates `apps/docs/src/docs/components/alert.md`, `apps/docs/src/docs/components/collapse.md`, `apps/docs/src/docs/components/dropdown.md`, `apps/docs/src/docs/components/modal.md`, `apps/docs/src/docs/components/offcanvas.md`, `apps/docs/src/docs/components/popover.md`, `apps/docs/src/docs/components/toast.md`, `apps/docs/src/docs/components/tooltip.md`	Added or updated Accessibility sections to reference centralized "ARIA Trigger Registration" guidance; reworked v-b-toggle/v-model guidance and moved/removed prior manual-ARIA notes and examples.
Directive docs `apps/docs/src/docs/directives/BToggle.md`	Clarified v-b-toggle behavior: directive registers triggers (aria-controls), target manages aria-expanded and visual classes via the show/hide system; expanded Accessibility and Usage guidance.
Accessibility reference (new/expanded) `apps/docs/src/docs/reference/accessibility.md`	Added extensive "ARIA Trigger Registration for component visibility" section: design, registration methods (v-b-toggle, v-model+v-b-toggle, manual), lifecycle, responsibilities, and component mappings.
Demo components (new) `apps/docs/src/docs/reference/demo/AriaRegistrationDirective.vue`, `apps/docs/src/docs/reference/demo/AriaRegistrationManual.vue`, `apps/docs/src/docs/reference/demo/AriaRegistrationProgrammatic.vue`	Added three demo Vue SFCs demonstrating directive-driven, manual, and programmatic ARIA/visibility patterns.
Architecture doc (new) `architecture/ARIA_VISIBILITY.md`	New architecture doc describing ARIA visibility patterns, data flow, internal API (register/unregister/check/watch), usage modes, testing, migration notes, and non-goals.
Directive implementation `packages/bootstrap-vue-next/src/directives/BToggle/index.ts`	Adjusted unmount behavior: call `unregisterTrigger(clean: true)` and remove only `aria-controls` on unmount; `aria-expanded` and collapsed/not-collapsed classes are left to the `useShowHide` composable; added explanatory comments.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

Focus areas:
- packages/bootstrap-vue-next/src/directives/BToggle/index.ts — confirm unregisterTrigger(clean: true) matches composable contract and avoids double-cleanup.
- apps/docs/src/docs/reference/accessibility.md vs. per-component docs — ensure guidance is consistent and not duplicated/conflicting.
- The three demo SFCs — verify they compile, type-check, and demonstrate the documented registration patterns.

Possibly related PRs

docs(Offcanvas): Parity pass #2900 — related docs and accessibility guidance adjustments for offcanvas and toggling behavior.
fix(directives): Robustness fixes for directives #2906 — touches the same BToggle directive and registration/unmount behavior.
fix(BToggle): stop looking for missing targets after directive is unmounted #2857 — earlier edits to BToggle unmount/cleanup logic; closely related to directive lifecycle changes.

Learning: In the bootstrap-vue-next docs codebase, the apps/docs/.vitepress/plugins/demo-container.ts plugin automatically generates kebab-case IDs from demo component filenames (e.g., CardKitchenSink.vue becomes id="card-kitchen-sink") and injects them into the HighlightCard wrapper elements. Therefore, demo components can use href="#kebab-case-filename" anchors without explicitly declaring the id attribute in the component template, as the id is generated at build time.

200-254: Documentation Examples section is well-structured and comprehensive.

The new section provides clear guidance on demo file format, code examples, and markdown references. The guidance aligns well with project conventions (template-first ordering, region markers, TypeScript in scripts). The example showing both template-only and script-based approaches provides good coverage of common patterns.

90-93: Architecture documentation path verified.

The ARIA_VISIBILITY.md file exists at architecture/ARIA_VISIBILITY.md as documented in the copilot instructions.

149-149: ****

The original review comment incorrectly claims a discrepancy between "PR objectives" (1643 tests) and the file documentation (1567+ tests). However, verification shows that "1643" does not appear anywhere in the repository, while "1567 tests" is consistently documented in both lines 149 and 196 of .github/copilot-instructions.md. The file is internally consistent and requires no changes.

Likely an incorrect or invalid review comment.

200-256: Excellent demo file format guidelines.

The new Documentation Examples section provides clear, actionable guidance with concrete examples for template-only and script-based demos. The region marker usage and demo reference syntax are well-documented.

Optionally address the markdown linting hints by:

Wrapping bare localhost URLs in angle brackets or code blocks (lines 29-31, 45, 47)

Adding a language identifier to the fenced code block at line 60

These are purely stylistic improvements and can be deferred.

Learning: In BTabs component (packages/bootstrap-vue-next/src/components/BTabs/BTabs.vue), the activeIndex synchronization within sortTabs() is necessary and correct. When sorting tabs by DOM position, indices change, so activeIndex must be updated immediately to maintain consistency with activeId. This is not an unwanted side effect but a required consequence of the sorting operation.

Learning: In the bootstrap-vue-next docs codebase, the apps/docs/.vitepress/plugins/demo-container.ts plugin automatically generates kebab-case IDs from demo component filenames (e.g., CardKitchenSink.vue becomes id="card-kitchen-sink") and injects them into the HighlightCard wrapper elements. Therefore, demo components can use href="#kebab-case-filename" anchors without explicitly declaring the id attribute in the component template, as the id is generated at build time.

apps/docs/src/docs/components/dropdown.md (1)

290-291: LGTM! Clear accessibility cross-reference.

The addition of the ARIA trigger registration reference is well-placed in the Accessibility section and maintains consistency with the broader documentation updates.

apps/docs/src/docs/components/alert.md (1)

71-74: LGTM! Accessibility guidance added.

The new Accessibility section appropriately documents ARIA attribute management for dismissible alerts and links to the centralized guidance.

packages/bootstrap-vue-next/src/directives/BToggle/index.ts (1)

122-128: LGTM! Clean separation of concerns.

The change from clean=false to clean=true correctly delegates cleanup of aria-expanded and CSS classes to the composable, while the directive retains responsibility for aria-controls. This architectural split ensures that dynamic state attributes are consistently managed by the component's visibility system, regardless of how visibility changes.

The added comments clearly document this responsibility boundary.

.github/copilot-instructions.md (1)

90-94: LGTM! Architecture documentation referenced.

The new Architecture Documentation section appropriately references the ARIA_VISIBILITY.md document, establishing a clear location for technical architecture guidance.

apps/docs/src/docs/reference/accessibility.md (1)

21-107: Excellent comprehensive ARIA documentation.

This new section provides thorough guidance on the ARIA trigger registration system with clear explanations of:

The opt-in registration model and split responsibilities between directive and composable

Three distinct usage patterns with concrete demos

When-to-use guidance for each approach

Component coverage with proper cross-references

The documentation effectively clarifies the architectural separation where v-b-toggle manages static relationships (aria-controls) while the visibility system manages dynamic state (aria-expanded, CSS classes).

apps/docs/src/docs/components/popover.md (1)

136-138: LGTM! Consistent accessibility documentation.

The Accessibility section appropriately references the ARIA trigger registration guidance, maintaining consistency with other component documentation.

apps/docs/src/docs/components/modal.md (1)

300-300: LGTM! Accessibility reference added.

The ARIA trigger registration reference is well-integrated into the existing Accessibility section, providing users with centralized guidance on managing modal trigger attributes.

apps/docs/src/docs/components/tooltip.md (1)

154-156: LGTM! Accessibility documentation complete.

The Accessibility section maintains the documentation pattern established across other components, providing users with consistent guidance on ARIA trigger management.

apps/docs/src/docs/components/toast.md (1)

82-83: LGTM! Documentation references are clear and consistent.

The addition properly directs users to the centralized ARIA Trigger Registration guidance, aligning with the broader documentation refactor across components.

apps/docs/src/docs/directives/BToggle.md (1)

2-28: Excellent documentation of the directive's responsibilities.

The rewritten documentation clearly explains the separation between the directive's static attribute management (aria-controls) and the component's dynamic state management (aria-expanded, CSS classes). This aligns perfectly with the architecture described in ARIA_VISIBILITY.md.

apps/docs/src/docs/reference/demo/AriaRegistrationDirective.vue (1)

1-8: Clean demo of automatic ARIA management.

This demo effectively illustrates Pattern 1 (v-b-toggle Directive) from the ARIA_VISIBILITY.md architecture, showing the simplest use case with automatic ARIA attribute handling.

apps/docs/src/docs/reference/demo/AriaRegistrationManual.vue (1)

1-27: Excellent demonstration of manual ARIA management.

This demo correctly implements Pattern 4 from the architecture documentation, showing developers how to manually manage all ARIA attributes and CSS classes when not using the v-b-toggle directive. The implementation properly synchronizes aria-expanded and CSS classes with the visibility state.

apps/docs/src/docs/reference/demo/AriaRegistrationProgrammatic.vue (1)

1-50: Good demonstration of hybrid v-b-toggle + v-model pattern.

This demo effectively illustrates Pattern 2 from the ARIA_VISIBILITY.md architecture, showing how automatic ARIA management (via v-b-toggle) can coexist with programmatic control (via v-model). The example clearly demonstrates both the slot-based hide function and direct v-model manipulation.

apps/docs/src/docs/components/offcanvas.md (1)

153-166: Clear and consistent ARIA guidance.

The updated documentation properly explains the division of responsibilities between the v-b-toggle directive (aria-controls, trigger registration) and the offcanvas component (aria-expanded, visual state). The reference to the centralized Accessibility documentation ensures users have access to comprehensive examples.

architecture/ARIA_VISIBILITY.md (1)

1-507: Outstanding architectural documentation!

This is exceptionally thorough documentation that clearly explains:

The rationale for separating static (aria-controls) and dynamic (aria-expanded, classes) ARIA attribute management

The opt-in trigger registration system and how it works

Multiple usage patterns with clear examples

Implementation details including data flows

Testing considerations and best practices

The document provides excellent guidance for both users and maintainers, with clear explanations of architectural decisions and their benefits. The four usage patterns align perfectly with the demo components added in this PR.

apps/docs/src/docs/components/collapse.md (1)

82-87: Well-integrated ARIA guidance for collapse component.

The updated documentation correctly describes how the v-b-toggle directive and BCollapse component work together to manage ARIA attributes, and appropriately references the comprehensive Accessibility documentation for detailed examples including v-model and manual ARIA management patterns.

@xvaara / @VividLemon I've marked this as a breaking change since I believe it technically is - if someone is doing some fancy footwork that depends on v-b-toggle itself to do the cleanup (although I think one would have to be abusing the system to actually have this code break you). Point is - we should think about this kind of case for once we've hit v1- my assumption is that had I tackled this exact problem post-v1 I could have done all the documentation changes and added a bug tagged next-major-rlease or something for the small code change.

Pull Request Overview

This PR refactors ARIA attribute management for show/hide components to eliminate redundancy between the v-b-toggle directive and useShowHide composable while maintaining all existing functionality. The key change is passing clean=true to unregisterTrigger() in the directive's unmount handler, allowing the composable to handle cleanup of dynamic attributes (aria-expanded and CSS classes) while the directive only removes the static aria-controls attribute.

Key changes:

Eliminated duplicate ARIA attribute cleanup logic by clarifying responsibility split
Added comprehensive architecture documentation explaining the trigger registration system
Updated user-facing documentation across multiple components with improved accessibility guidance

Timestamp: 2025-09-30T23:57:21.526Z
Learning: The bootstrap-vue-next documentation project uses unplugin-vue-components to automatically resolve and import Vue components like BModal, BButton, etc. Explicit imports for these components in script sections are not required.

File: apps/docs/.vitepress/plugins/auto-inject-doc-components.ts:106-130
Timestamp: 2025-10-28T03:37:33.172Z
Learning: In apps/docs/.vitepress/plugins/auto-inject-doc-components.ts, the documentation injection logic is intentionally simple and does not need to handle edge cases like partial presence of ComponentReference/imports, existing <script setup> blocks, or nested component directories. The codebase does not use these patterns and does not expect to support them.

Timestamp: 2025-10-21T19:26:36.699Z
Learning: In documentation example files under apps/docs/src/docs/components/demo/, keep examples simple and focused on demonstrating the specific feature, even if the implementation is not production-ready. Avoid suggesting complex implementations that would obscure the main point of the example.

File: apps/docs/src/docs/components/demo/CardKitchenSink.vue:28-31
Timestamp: 2025-10-21T01:11:59.901Z
Learning: In the bootstrap-vue-next docs codebase, the apps/docs/.vitepress/plugins/demo-container.ts plugin automatically generates kebab-case IDs from demo component filenames (e.g., CardKitchenSink.vue becomes id="card-kitchen-sink") and injects them into the HighlightCard wrapper elements. Therefore, demo components can use href="#kebab-case-filename" anchors without explicitly declaring the id attribute in the component template, as the id is generated at build time.

248-248: Documentation examples section adequately clarifies demo file references.

The updated guidance at line 248 clearly shows that #region name markers in demo files are referenced as #name in markdown. The concrete example (#region template → #template) directly addresses the ambiguity flagged in prior reviews.
