Widget layers are used to stack widgets over each other as needed. For example to move your quotes widget above to the top layer so you can see it over an image widget that you want behind it.
Steps:
Log into your Mango Display account.
Click on the display you'd like to edit.
Then at the top of your display next to 'Clear Page', click 'Widget Layers'.
Edit your widget's position by dragging the layers on top of each other.
*Here's an example of how your widgets should look like once your changes are applied: (Quotes on top of GIFs & Stickers)
