Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).

I saw the screenshots you attached. The Html Blocks are not set to work for the mobile menu.

You need to create a separate menu for mobile and use the sub-categories as the sub items from Appearance >> Menus.

Then set the menu as categories from WoodMart >> Header Builder >> Edit Header >> Mobile header.
