Hi, Could you provide a code snippet for your case? In our demo application exactly the same behavior of the sidebar and background overlay are presented on the following page: Navigation -> Pro -> SideNav and I'm surprised that clicking the background mask doesn't toggle your side nav by default. Kind regards, Magdalena

I saw you added an id to the mask, so I was able to add a listener for this:

document.addEventListener("click", function(e) { if (e.target && e.target.id == "sidenav-overlay") { app.toggle = false; } });
