Menu Closes When Clicked

I see, the problem has nothing to do with the menu accordeon
you have an overlay when opening the mobile menu (off-canvas) that makes it close when you can click ANYWHERE in the page, you can test yourself
The event registered is

function(event) {
event.preventDefault();
$('.off-canvas-menu-init').removeClass('offcanvas');
}

this makes it close on click

Thank you very much for identifying...any chance you know how to remedy this?

I tried removing the .JS, but that stopped the menu from opening. I then tried to hide the overlay via CSS call - no dice.

Any suggestions would be greatly appreciated!!!

Thank you very much.

I also noticed that this .JS is installed on another site I am working on and this does not affect the menu - could it be something else?

sorry but this is totally out of my scope, you must manage that in your template or off-canvas menu ...
it seems that there are also other JS events launched in the off-canvas menu

function() {
$('.off-canvas-menu-init').removeClass('offcanvas slide-top-menu full-screen-off-canvas full-screen-off-canvas-ftop new-look-off-canvas');
}
