Antention: Custom main menu won't show sub-menu on mobile menu

[bandzy]

Hello all,
I just find out that custom menu for main menu don't show sub-menu.

But It can show if you name your main menu name as "topmenu"
So who have this display problem rename you main menu.

I think this is an issue with Wordpress in general, but thanks for pointing it out and letting others know how to fix it
