I currently have a lot of buttons on my side menu and I wanted to group them, as the heading suggests I want to create a side menu with collapsible submenus of buttons using expander.
I created the side menu but with no idea how to make it collapsible, googled a lot but found nothing.
Can somebody help and show me how to create it?
What I wanted was something like this:
C# WPF Design UI - Dropdown Menu
but unfortunately it is using MVVM model which I don't use.
