I would like to create a menu with a description of the menu like megamenu. My menu looks like the following model:
How can I create this?
You could try Ultimenu
Ultimenu is the UltimatelyDeadSimple™ megamenu ever with dynamic region creation.
An Ultimenu block is based on a menu. Ultimenu regions are based on the menu items. The result is a block contains regions containing blocks, as opposed to: a region contains blocks.
You can try TB Mega Menu, it's got very nice user interface (WYSIWYG) and also multiple built-in styles.
You can use OM Maximenu to add description or block or menu inside menu.its quite simple and best to add like your design
