SideMenu open / close

I have a div in the sidemenu that has html divs within. Used to call a url on click. This works but I also need the sidemenu to close is screen size is less than 400.

On mobile portrait once the new control is opened I cannot close the sidemenu.( unless I click another item ).

Is it possible the click is not passing through the htmlDiv?

Can you please describe this more precise, preferably provide some sample source app.
When you refer to HTML DIVs within, is this DIVs added via TNormalSideMenuItem.HTML?
When you refer to an URL? Is this an URL in these DIVs added via HTML?
