Joomla not Showing Dropdown SubMenu to SubMenu?

Question

I created a dropdown menu in my joomla website. I created the menu like this:

Parent-1
     sub menu-1
              sub menu-1
              sub menu-2  
     sub menu-2
     sub menu-3
     sub menu-4
parent-2
parent-3
parent-4

This is how I created the menu, but joomla shows only the parent of submenu not showing the submenu of submenu.

What can I do to fix it?

Answer 1

It should work with this configuration, in the back-end go to "extensions" -> "Module manager" -> "the name of the module which linked to the menu"
