Main Menu-Sub Menu Drop Down (on the bottom) possible?

Hello,

Love the Minimatic theme! Am currently testing it out to use for my portfolio.

Instead of a bottom menu I’m using a top menu. However, in the main menu, the dropdown menu for sub categories for example is dropping down (or up to be exact) towards the top side, which in case of a menu item with more than one sub-category not all of them will be visible.

Is it possible to change this drop ‘up’ menu so to speak to drop down instead? I hope you can make sense of what I’m asking. I’ve looked in the css file but can’t figure out what to change to make this happen. The link to my site is [url=http://anilcherukupalli.com/port]here[/url].

Many thanks in advance for your help!
