Context

As we're slowly starting to roll out new versions of existing components, we want to start gathering feedback on what changes, improvements, and new features we'd like to see applied to such components.

While we initially focused on Tooltip (shipped), Tabs (almost ready), and DropdownMenu (still WIP), we think that the next batch of components that we'll focus on is going to be CustomSelectControl, ComboboxControl and FormTokenField.

We see these three components as related:

• CustomSelectControl is the first component in the group that we'll focus on, since it is the simplest of the three;
• ComoboxControl will come after, since it kind of builds on CustomSelectControl and adds a text input to search through the options;
• FormTokenField will be the last component of the group, as it's the most complex, and kinda builds on top of ComboboxControl, adding the token "chips".

Feedback

I will update this section as we gather feedback.

• Make the token component support non-text elements, like images (source)
• Make the token component support non-text elements, like images (source)
  • Either via slot + subcomponents, or via a function/render prop? Same as CustomSelectControl V2 with renderSelectedValue
• Support error and loading states (source)
• Make tokens optionally dismissible (source)
• Make it possible to search by label, id, slug, SKU, author, and other meta-data (source, Allow FormTokenField suggestions to use keywords #33334)
• Display secondary meta-data when two tokens with the same label are added, e.g., ID or Slug (source)
• Ability to display explicit action for creating items, currently triggered by comma or Enter key. Potentially, it could help us resolve Saving tags before post creates unused/unwanted tags #15406. (source) (source)
• Allow separation between item values and displayed UI, support custom JSX (source) (source)
• [FormTokenField] Close the form when the number of tokens reach maxLength #42773
• Better copy/paste support? Allow FormTokenField to be selected and copied #35940
• Better sort order Sort order for FormTokenField #22048
  • Related to "Display handles and make it possible to reorder tokens by drag & drop" (source)
