ok, I thought RokNavMenu had a "number of child items" option but I don't believe it does... I think I was thinking of the WordPress menu system...
in any case, I would say just kill the drop down entirely with some custom css... just target the dropdown container while it's IN the normal position... lets assume Header
#rt-header ul.gf-menu > li.parent > div.dropdown {
display:none;
}
That WON'T apply in mobile mode because the entire menu structure is removed the Header position and is placed in the mobile wrapper designed for the sidepanel menu...
