Does the Pro Version allow Automatic Drop Down to Be Drop Up?

On one of my sites, I have many pages. In some cases, 5 tiers of sub menus. In general I notice the computer will decide if there is room to display the next tier DOWNWARDS or UPWARDS. But with Mega Menu it only goes DOWNWARD. This means in some cases, many of the entries are not displayed because there is not enough screen room at the bottom of the window. I haven’t yet purchased the pro version and there is not way for me to make such an inquiry to the owners of the plugin unless I have the pro version. I’m wondering if anyone knows that if I were to get the Pro version of this plugin, would it auto-detect if there is room to display the next level sub menu DOWNWARD and if not, that it would display UPWARD? (This would be really cool.) Thank you!
