My site has several pages, organized in a tree structure. The sub-menus of the top items are not indented, so for children of items beyond the first item, it can be hard or impossible to move the mouse over the children. I’ve worked around this by adding the following to the style.css, but this is dependent on manually choosing suitable offsets.
#topnav li:first-child + li .children { margin-left: 100px; }
#topnav li:first-child + li .children .children { margin-left: 0px; }
#topnav li:first-child + li + li .children { margin-left: 170px; }
#topnav li:first-child + li + li .children .children { margin-left: 0px; }
#topnav li:first-child + li + li + li .children { margin-left: 280px; }
#topnav li:first-child + li + li + li .children .children { margin-left: 0px; }
#topnav li:first-child + li + li + li + li .children { margin-left: 400px; }
#topnav li:first-child + li + li + li + li .children .children { margin-left: 0px; }
#topnav li:first-child + li + li + li + li + li .children { margin-left: 470px; }
#topnav li:first-child + li + li + li + li + li .children .children { margin-left: 0px; }
#topnav li:first-child + li + li + li + li + li + li .children { margin-left: 600px; }
#topnav li:first-child + li + li + li + li + li + li .children .children { margin-left: 0px; }

Hi,

I am using the Ming theme on this wordpress site.

When viewing the site on a mobile or tabet the button to open the title menu appears but when I click it the menu does not appear.

Any suggestions why?

Thanks,

Clement
