I am using an HTML Blocks for my main page menu items. However, the menu items are being cut off when you click on them on the home page. This is due to the number of items I have on the submenu HTML Block. I tried for days now to add a scrollbar to the HTML Block submenus using their class names without success. These submenus are linked to the “Browse category” menu container on the home page. I tried creating class names for the actual HTML block, or the submenu item in Appearance and none of those classes respond .How do I add scrollbars to my submenus HTML blocks?
