two column slideout menu

Hmm, there probably wouldn't be much room. Do you have any examples of others doing this I can see?

I am using a menu image so there will be enough room. I had this for the drop down menu but want it to work for the slide out menu
.toggled .main-nav .sf-menu>li{float:left!important;width:50%;clear:none}
thanks

Try this:

.slideout-navigation .main-nav .sf-menu>li{
    float:left!important;
    width:50%;
    clear:none
}
