A way to use already defined tags/categories

[josineto]

Hi, I'd like to know whether it's possible to configure a widget to use fields already used in the site. The most obvious example is with categories and tags. For instance, a list of tags for a post in which each list item has a dropdown with all existing tags in the site.

It seems to me a bit linked to the relation widget. A more difficult way to achieve that would be to create a collection for tags (to keep the same example) and retrieve that collection in a relation widget. But this way it would be necessary to create a new collection item each time a new tag is defined, what would be not practical.

To explain it in details, keeping the same example:

• I create a new post.
• When I have to type the post tags, the (desired) widget shows me all site tags.
• I then choose between these and/or to define new tag(s).
• If I define new tags, these are shown in the widget the next time I create a post.

I think the best way to it (from UX POV) would be a delimiter separated list (as implemented in 2.4.0) that suggests already defined values in a dropdown as I type. But I don't know whether that is practical or even possible from a developer POV...
