Clicking on a panel (not only on the title)

[bgadrian]

Hello,

I can make a PR to improve the UI a bit:

I think that the entire head/panel should be responsive, not only the title. It is something that a User would expect when using a collapsible menu (accordion).
Meaning: you can click the grey area to expand/collapse the category contents.

It is ok?

Yes, that would be good, thanks.
