Add a field (Sql or List) in article options with a search bar inside in Joomla 4

Question

I added a field type "sql" to show a list of options in the Article Options in Joomla 4. But I need to add a field like this with a search box inside to looking for one of the voices typing part of the options (because the options are many).

So, I need something like this:

I noticed that in Joomla 3 someone used "formbehavior.chosen" to do this, but this function is applied to every list in the Article Options, and I don't want it. I want this behavior, this search box in a list, only for a specific list.

Is there a way in Joomla 4 to do this in a simple way? Can I just set an attribute in the field element of the XML file to do this? Thank you :)

In J4 you can use joomla.form.field.list-fancy-select layout for list fields. To use in XML form, add layout attribute to the field:

layout="joomla.form.field.list-fancy-select"
