Show/hide menu panel with JavaScript in Storyline 3.

Hello. 

I've spent some time digging around this thread regarding the same topic; however, much of the advice no longer applies after semi-recent SL3 updates. 

After importing JQuery using the first method here and using the following code,  I'm only able to toggle the opacity, but I can't close/minimize the sidebar entirely.

$('#sidebar').animate ({ width: 'toggle', opacity: 'toggle' });

Has anyone else been able to get their sidebar to close entirely?
