What happened?

Description

The button that lets you order link field types shows an empty menu when there's only one type enabled

Steps to reproduce

1. Create a link field type
2. Tick only one of the types
3. Click the "..." button next to that option

Expected behavior

Either don't show this toggle button when only one option is enabled, or show but disable the options.

Actual behavior

A weird looking empty menu:
