Feature : Refactor Autocomplete using DropdownMenu

[Vrishabhsk]

What?

• Refactor Autocomplete component using DropdownMenu instead of custom ListBox

Why?

• Autocomplete: Refactor to use DropdownMenu #64323

Issues

• The Type / to chose a block text disappears when the / is erased
• After typing /, it works perfectly but when the popover is open, and we switch tab or the window and return to editor and remove the /, an error is thrown which breaks the block.

Hi @mirka 👋

• I have refactored the Autocomplete component as per this issue : #64323
• There are some issue which I need guidance upon mentioned in the PR description.
• Due to the blockers, this isn't the final version of the implementation, ill be updating the docs and tests once the feature looks good to me.

I was wondering if you could help me with resolving these blockers? Thanks

Hey @Vrishabhsk , thank you for the work so far!

Before diving into detailed code review, I have some high-level feedback:

• the original issue called for using DropdownMenuV2, if possible — you're using DropdownMenu instead (sorry if that part was confusing!)
• regardless, I'm not sure we can use the DropdownMenu (or DropdownMenuV2) component in their current state, since they both render a visual trigger, while (from what I understand) Autocomplete doesn't currently come with a trigger button (in the editor, in fact, it can be triggered by pressing the / shortcut)

Having said that, if we tweak DropdownMenuV2 to expose the "menu in a popover" part separately from the "trigger" part, we may be able to actually rewrite `Autocomplete.

Alternatively, we could simply deprecate Autocomplete and refactor its usages in the editor with said DropdownMenuV2 subcomponents.

Does this make sense, @mirka , or am I misinterpreting the task?

Hi @ciampo 👋

• Initially, I had used DropdownMenuV2 but due to several issues which I encountered, I instead used DropdownMenu
• The visual trigger in this case has been handled by defaultOpen and open attribute which keeps the Dropdown visible at all times.
• The dropdown will be visible only when the Autocomplete component is rendered
• The icon attribute in DropdownMenu has been set to <></> which prevent the trigger from appearing
• You can view the implementation via DropdownMenuV2 : DropdownMenuV2 Refactor

Let me know the further steps here. Thanks

I'd like to hear @mirka 's thoughts too before deciding next steps.

In any case, if we were to use a dropdown menu implementation, I think it should be the V2 (which, by the way, is still experimental and is currently undergoing major API changes like #66289 and #66383, which should let us avoid hacks like rendering empty fragments for the icon trigger etc).

I had a quick look at your refactor and could spot a few parts that need changing. More in general, I believe that using the dropdown menu component may require a bit of a deeper refactor than simply swapping in components.

@ciampo This sounds good to me. I remember at some point we were talking about replacing the trigger prop with a subcomponent anyway.

In this case, next steps would be to make changes in DropdownMenuV2?

Yup! Working on these changes in #66383, will ping you all once they're ready for review
