Selection Limit
If there's a selection limit, please consider the following:
Keep the multi-select input enabled at all times.
Do not disable the input field itself, this can be unexpected and may cause the menu to close abruptly.
Ensure the user can still deselect items even when some options are disabled.
Disable all other items instead
Show help text explaining why some options are disabled.
If the selection limit is static, always show the help text.
If the selection limit is dynamic, show the help text only after the limit has been reached.
