You can achieve this by layering. I often do this to show the user avatar instead of the hamburger, and make it so clicking on the user’s avatar exposes the slide menu:
- The slidebar menu has an option to show icon–uncheck this. This leaves the slidebar element on the page, but in effect hides it from the user.
- Then place any icon or image “inside” the slidebar element.
- Select the icon element, and in the top menu choose “Send to Back”:
- …and to be extra sure select the Slidebar element and choose Arrange–>Bring to Front.
The user will “see” the icon, but when they click, they’ll be clicking on the “invisible” slidebar element sitting on top of the image, which triggers the menu to display.
