How does it work?
Playlist in playlist offers an option to embed playlists into playlists. We call these embedded playlists “sub-playlists” and the playlist that contains sub-playlists is referred to as master playlist. Altogether the functionality is called zoning as you can create zones on your screen that change content individually.

FAQ
How do I create multiple zones that fill in the master playlist completely?
Check out our article on creating custom zones.
How many levels can the playlists be nested? 
The playlist can be nested to 1 depth level. In other words, this means that the sub-playlist can not have a sub-playlist of it’s own. This is because each instance of a playlist consumes a lot of resources and to also prevent users from creating infinite loops where two playlists reference each other.
If I make changes in a sub-playlist, do I also need to publish all parent playlists that contain the sub-playlist?
You don’t need to explicitly publish every playlist, when you press “Publish” on the sub-playlist, the system will automatically also publish all playlists that contain the sub-playlist.
My sub-playlists are not nicely formatted?
When you create custom zones one by one manually rather than using a pre-made layout, the system does not know which playlist is a child of which (and also you can include same playlist in several other playlists). Therefore the sub-playlists will not be formatted nicely as in the screenshot above, but do not worry – the formatting is only eye candy, all functionality still remains the same.
