Based on the comment here [1], I find the following simple method to
capture a drop-down menu:


Install the imagemagick package, then issue the following command on a terminal:

$ sleep 10; import -window root /tmp/screenshot.png

In the next 10 seconds change your active window, open the dropdown
menu and wait. You will likely need to crop your screenshot
afterwards.
