Is there a way to make a popout menu 'stick' when inspecting with Firebug.
You can do it with Chrome, but I prefer firebug.
It's hard to set padding or a margin when you can't see the element you are styling.
I did some research but couldn't figure it out.
There's an option built in:
Inspect the element that's "hidden", then use this.
You can show/hide them using JS console, directly using show() or binding an event(mouseover, click etc).
