Mobile: menu drop down with sub albums closes before selection

[dmfisch]

Hello!

I love this theme, thank You very much, but there is a problem on Mobile: the menu drop down with an album with sub albums closes before selection

feel free to look it up on

The menu item Photography is an album with sub albums,
the menu drops down and closes before ay selection is possible

The menu item VR 360° has additional pages and the menu drops down and stays until a selection is made

Best regards,
David
