Accordion in NavigationDrawer in Xamarin.Forms

You can load the SfAccordion to the SfNavigationDrawer in Xamarin.Forms Accordion

Load the SfAccordion into the SfNavigationDrawer.DrawerContentView and bind the ViewModel property to the SfNavigationDrawer.IsOpen property to open the drawer. Add hamburger icon to the Image with Image.GestureRecognizer and bind the ViewModel command to the TapGestureRecognizer.Command to toggle the drawer.
