I am currently building a website with my own custom theme. I have used WordPress Menus to create a nav menu on my own. The submenus are being generated as I can see them in the HTML source file of the webpage. But, I do not know how to display the submenus as vertical dropdowns on hovering over the main menu items. Please help me out in the css I need to add to make them work.
Alternatively I tried using Shailan dropdown menu plugin. Now I can get the submenus on hover, but they are generated as Horizontal rather than vertical dropdown.
Please provide me some insight onto how I go about achieving this.
