Datalist is not a suitable replacement for Chosen. It's fine for text fields (already implemented in J3).

In J4 Chosen is already replaced by Choicesjs for multi-select and single-select uses nothing (can use Choicesjs as well if you need its features).

I am using J4 beta 1 and I cannot see any advantages on JS choice over datalist

J4 is not using chosen it is using choices

in some use cases datalist could be used but not in all the places that joomla uses selects

For reference the requirements are

1. accessible
2. select multiple
3. create new option on the fly

Datalist provide possible options for text field.
It's no replacement for a select list as it doesn't restrict the input to the datalist options as a select field would.
Chosen and choices both work on select lists, not on regular text inputs. So it's something completely different, allthougt looking similar.

Datalist and Choices are 2 very different things. The former being extremely limited and rather buggy. They had good intentions implementing this element, but it's not very good at what it does.

there is a possibility with js to do a multiple select on datalist (for now)
but it was only a suggestion
thanks to all
