Autocomplete option for dropdown field
What are you trying to do? Would be really nice to have an autocomplete field type. There are certain use cases (such as countries listed in a dropdown), that although they work, are not necessarily the most user-friendly experience on mobile devices, which require scrolling through dozens of (hopefully alphabetical) options. An autocomplete field would allow users to type a few characters and select their preferred option instead, which should be easier overall.
What's your proposed solution? I envision this being its own field type. It would have the ability to define and bulk add options in the same mode as dropdown fields, as well as the ability to define single or multiple select. Single select would display similar to an address field with an address provider enabled, with a list of options provided after a few characters are entered. Selecting an option would populate that value into the field. Multiple select would be very similar, but selected values would be populated as "tags" with a UI element for removing them (like how states are added to a shipping zone in Craft Commerce).
This could also be offered as a Display Type for Element Fields. Again, this would greatly simplify data entry for users in situations with many options, for example when a retailer has numerous product offerings.
Nice feature request! I think my preference might be to add "Use Autocomplete" setting for a Dropdown field, which when also setting to "Allow Multiple" provides the usual multi-select behaviour you see in things like Select2. I just want to ensure we keep a lid on the amount of fields provided to users, so we don't overwhelm people with options. That, and the functionality is all there like bulk adding, etc for a Dropdown field already.
As you mention, this would also flow-on to any field presented as a Dropdown like element fields, or Recipient fields.
In fact, we currently use tagify for the Tag field, so all the parts are there.
