Currently the Bootstrap addon supports just navbars since by default they have very similar HTML markup to what SmartMenus needs – a regular unordered list. And SmartMenus’ main use case is as a global website menu which in Bootstrap corresponds to a navbar.
There are a few other cases where Bootstrap supports dropdowns but they use pretty different markup – i.e. they have a separate target element that triggers the dropdowns, etc. Possibly, in the future, the addon might be enhanced to support those cases too (via popup menus http://www.smartmenus.org/docs/#isPopup) but it’s not as straight forward as just supporting navbars.
