Hey there! New to framer, and my favorite command so far is "visible = true/false", as I'm generally just importing my design elements from Sketch, then showing/hiding them with various Click events.
I haven't yet figured out how to toggle a show, however. For example, clicking the same expand/collapse button should show or hide the elements below it. Once I get an element to show, I'm not sure how to hide it again (I've tried using "if element.is(":visible")", but that doesn't work).
I know framer.js is much more powerful than this though, so I'm open to other ways of skinning the same cat.
