The Master page feature gives an opportunity to the users to put elements behind every page of a content.
For example the user does not need to set the same background image on every page in the content, it is enough if the user creates a Master page and select the image as background on this page.
Users can set the Master page in the editor under the Content properties.
There are 2 types of Master pages.
First is a simple Master page, which can be created in the content’s page list. This Master page can be only used in the content where it was created, and can be modified like a simple page.
The other option is, that the user can insert a Content, a Loop or a Schedule as a Master page.
Overlay page is needed if the user wants to display widgets over the content.
Every elements, contained by the Overlay page, will be displayed over every page that the content has.
Overlay page can be created in the content’s page list and can be modified like a simple page.
