How to create stackoverflow type buttons?

Question

I would like to know how to create stack overflow type buttons (buttons like in image below)? Is it possible to create buttons like this using ExtJS?

Answer 1

Someone made an extension for that awhile ago.

It is not exactly like SO buttons but you could play around with the CSS a bit and possibly add a few overrides to get it 100%.

I think the fourth example (forceSelection: false) is probably the most similar. Just hide the field box and change the close icon and you're basically there.

Here are the examples.

And here is the thread.
