Provide way to add an item during "Selecting a ForeignKey"

[guettli]

I use django-select2 for easy ForeignKey picking. Works nice.

But how can I add a new item in the ForeignKey table?

I would like to have a big [+] button and then a dialog should open.

AFAIK django-select2 does not help here. Is there a different library which can help here?

The result should look like this "create user" example: https://jqueryui.com/dialog/#modal-form

I don't care how the pop-up works.

Via ajax, browser pop-up, or like in django admin, ...

It should work and be re-usable. I don't want to invent this common pattern again and again.

I found that django-autocomplete-light supports "Add another popup outside the admin":

This is exactly what I was looking for :-)

Just for the records: "add another" is one compared feature in this comparison grid: https://www.djangopackages.com/grids/g/auto-complete/
