I'm on the hunt for something akin to the following: An input-box, where I can type something, and if it already exists, it will show up, and if not, I can leave it, and it will be created (this is for selecting or creating folders, but that is the background process, and that is fine). I'm just wondering if anyone knows of anything like this already available? I'm thinking I maybe need to search for something akin to taxonomy or similar when searching, because I currently have next to no luck on Google.
https://jqueryui.com/autocomplete/ calls a back end process which returns json I'm able to return display text and an id so that the user might select a name but the form stores an id.
Hm, I'll look a bit more into that, @sarahk - I might be able to use that for what I want, although I might need to rewrite some of the rendering-options (I want the existing dropdown showing when the user clicks the input, for instance, not having to either type something or click a button to get the existing drop-down - probably doable).
