Some themes have a demo fly-out menu to show colors, typography, etc.

Is there a plugin that does this? Can’t seem to find one. Thanks in advance.flyout

It’s a few jQuery codes usually changes or add CSS codes. I’m not sure if someone has already created a plugin/extension but you can check CodeCanyon

Thanks for replying. Actually, I’m not interested in changing CSS. I want the space to add images, video, etc. I’ve checked Codecanyon for ‘side flyout menu’ and ‘side menu’ etc. but what it finds are social media menus and nav menus, not content menus.
