The Layer Tree is where you are able to view all the components you've placed on a screen, rearrange them, and see their relationship with other elements.
To add components to the Layer Tree, click the '+' next to
Layout to launch the component picker. In this menu you can click to add components to the Layer Tree.
To rearrange components, simply click the component in the Layer Tree, drag it and drop it where you would like it to go instead.
To delete a component, duplicate a component or create a Custom Block, click the '...' next to the component name to launch a context menu.
