I found help here. https://github.com/vadikom/smartmenus/issues/16
(wasn’t using button groups but was using columns inside bootstrap dropdown menus for some items)
so added “data-in-mega_smartmenus=”true”” as shown below
<ul class="dropdown-menu">
<li>
<ul class="list-unstyled col-sm-6 nav-border" data-in-mega_smartmenus="true">
<li><a>Great Plains IDEA Directory</a></li>
<li><a>Lead Institution</a></li>
<li><a>Functional Teams</a></li>
<li><a>Human Sciences</a></li>
<li><a>Board of Directors</a></li>
<li><a>Campus Coordinators</a></li>
<li><a>Program Contacts</a></li>
</ul>
<ul class="list-unstyled col-sm-6" data-in-mega_smartmenus="true">
<li><a>AG IDEA</a></li>
<li><a>Executive Committee</a></li>
<li><a>Campus Coordinators</a></li>
<li><a>Program Contacts</a></li>
</ul>
</li>
</ul>
