The MaterialDrawer library uses the FastAdapter as adapter behind the scenes to offer expandable functionality, and additional APIs to simplify the work with the RecyclerView showing the elements.

To collapse all expanded items within the drawer, it is possible to access the expandableExtension from the MaterialDrawerSliderView, and use its API to for example collapse all items.

binding.slider.expandableExtension.collapse()

To connect this to the Drawer, call this for example when the Profile item was clicked and you were notified via the onDrawerItemClickListener

The provided sample code is based on the MaterialDrawer v8.x.y version
