Disregard. I had been converting a bootstrap menu and had tried using the jquery.smartmenus.bootstrap.js, but in converting, didn’t need the bootstrap stuff. This was still there though and causing the dropdowns to not work right with a justified nav.
I’m currently trying to switch a site to use this menu, but if I try to make the nav justified (using the table, table-cell) method, I lose dropdown functionality. I could overwrite the submenu CSS and force it to work, but is there better way of making this work?
