Create Reference
Navigations and footers can be marked as references. This creates a copy of the component under Favorites > References, which can then be used on all subpages. This means that you do not have to maintain the component on every page when you make a change to it.
Open the Layers menu in the right sidebar.
Select the component you want to reference, such as the navigation.
Click on the three dots next to the component in the Layers menu.
Click on Create Reference.
You can now add the reference component to the remaining subpages. To do this, go to Favorites > References. Drag the component into the canvas.
You can now add the reference to all subpages. If you change it anywhere, the customized component will change on all subpages.
