I have copied and pasted the example code from your site for the Close button that you can add to the Off-Canvas menu. But for some reason it is not working. I created a codepen here:
The menu button to open the off-canvas menu works just fine and also can close it. But I was wanting to use the overlap menu (data-transition=“overlap”) but then on mobile the menu button would be hidden, so I would need a close button. But I just cannot figure out why it’s not working.
