Info Menu Custom widget area
InfoMenu → Custom widget area
Create a new Info Menu item for any widget (or shortcode via the React Shortcode widget). Click Add widget area and give the area a name, which will be the name of the widget area (not to be mistaken with the items title – see below for title).
Once it is created you can locate your widget area in WordPress → Appearance → Widgets and add your widgets.
For each area you can choose to display the content (in this case a widget) in either a Pop Out box or in a Slide Out box.
Choose a title name for your section, which will be shown when the area is open and when user hovers over the menu item.
Choose an icon from the selector that will represent this item in the menu.
