Only allow one dropdown at a time. Automatically close all others when opening a new one, so we prevent overlap
Only close all when we are mousenter on data-dropdown, not data-dropdown-content
Ignore Codio's .settings file
Don't close others if the new dropdown is_hover:false. This way if we move the mouse too far, the dropdown doesn't close
