Hi @Darshan Saini ,
Good Day!
Please follow the below steps for creating the SideBarCollapseMenu .
Are you building a Reactive Application? If yes, the LayoutSideMenu has 3 different behaviors!
1- In your Theme bind the correct Layout

2- The SideMenuBehavior - Overlay, starts with the menu hidden and can be opened using the hamburger icon

I hope this helps you.
