Jquery Megamenu plugin with horizontal submenu items

I am looking to find a header menu jquery plugin that supports multilevel items but sub menu items are placed horizontally.

e.g Category 1 has 80 subcategories. When the Category 1 is hovered and a submenu opens up and the 80 subcategories should be placed horizontal instead of vertical which is impossible to read as they create a long scroll page.

I have been searching for hours but cant find anything similar to my requirement.
