There is http://quasar-framework.org/components/uploader.html so I think this is kind of intended.
And also what should be displayed in the input? It would be more like a button and does not integrate well with the q-input design.
But maybe @rstoenescu can tell you if it is intended.

There’s a planned feature to have Chips Input work with Autocomplete.

Excellent, it worked. I had some old conf.js files…

Thank you!
