Combobox: List selected items with badges/input chips

[pardeyke]

I really love the new combobox component, especially the search feature. I was really looking forward to replacing use-bootstrap-select for some time, and this might be the opportunity.

A feature that is very popular all over the web is select boxes with multiple inputs and a badge-like appearance for the selected items in the closed select box—something that visually looks like the new input chips. I think it would be beneficial to merge the presentation of the input chips into the combobox. In the best case, this would also include the ability to add new items. I know the new-items feature is highly dependent on your backend, but it could perhaps just trigger an event. This could then be handled in JS per backend or maybe there is a general approach to this.

For reference:
On my Ruby on Rails backend, I currently handle this by submitting the new item (let’s call it “Orange”) in the id field (id=“Orange”).
I have not implemented this with multiple new items, though.
