Conflict with Ultimate Posts Widget

Hello,
when i’m trying to add a widget in the mega menu windows (Menus -> Selected Item -> Mega Menu -> Select widget to add to panel), and the widget has Tabs in it, the tabs are disabled and becomes none-clickable.
Unfortunately all professional widgets has tabs, and if that has a conflict it will be a problem.
Please install “Ultimate Posts Widget” and try it out.
However, i suggest to let the user add widget section instead of stand alone widget, that would help by customizing the widget outside, and just call it in the menu.
