I want display my website on mobile like a desktop version. But my drop down menu not active .
Please let me know how to adjust.
Unfortunately, the submenus do not work for mobiles with the responsiveness option turned off.
In that case, you should use a menu with 1 level of depth.
menu setting / display location / depth 1
Can't fix the problem
I meant that your menu should not have submenus if you do not want to have the responsive option enabled.
So the menu should be one level without the submenu.
