Hello @sax and thanks for the contribution! I have a question and a couple of suggestions:

Question: why is this slot attribute a list?

Suggestions:

1. It would be nice to have a default implementation of the caret, turned off by default but that people can turn on if needed
2. Styling of the caret should follow the styling conventions of the rest of the library, so I would add a caret_class and caret_extra_class options like for the other elements.
3. There need to be tests that check that you can override the caret slot and set the styling attributes for it. The former tests are in live_select_test.exs and call the LiveComponent in live_component_form, to which the caret slot will have to be added. The latter tests live in component_test.exs.

Let me know if you need any help or have questions! Thanks

Sorry for the delay. I set the :class attribute on the slot to be a list because heex rendering treats attributes as iodatas rather than strings. Maybe there's a way to declare that, so people can use either strings or iodates.

Yeah, I was having issues understanding the test setup. Thanks for pointing me in a direction.

I have a set of tailwind classes that can be used as a default, but I am unclear what a daisy UI version would be.

daisyUI uses tailwind so very likely you could reuse the same classes
