In my application, I have a series of radio buttons. The associated labels can contain a number of fields and become quite long, so I'd like for the labels to be expaneded and collapsed.

I've considered adding a toggleable +/- button to the left to allow the user to expand the section and see the full label:

However, I'm worried that the +/- icons on the left will be too close to the radio buttons and cause errors or confusion, so **how should I allow the user to toggle the label collapsibility**?
