Hi.
Unfortunately no, I haven't been able to solve my problem. I did some progress though (I guess). Whit what I had before, I could select a tag, then select another tag and the previously selected tag would be unselected. But then it would stick to that tag no matter where I clicked. I couldn't select any other tag and the one tag wouldn't be deselected either.
With what I have now, however, my list of tags behaves more like a checkbox group: you can select as many tags as you want. But that's not what I want either.
I think a better example of how I want my list to behave is the Button Group widget rather than the Radio Group.
Your example does work, but I think it doesn't visually show the item you selected. I want the tag's background color to turn another color when it is selected.
Truly appreciate your help.
