Create a new estate list and give it a name, for example “Favorites”. In the box “Filters & Records”, set the “Type of List” to “Favorites List” and save it.
Copy the shortcode, create a new page and paste the shortcode. When you preview the page, you should see an empty favorite list, because you have not yet added any favorites.
In “onOffice > Settings”, check “Enable Watchlist”. The included templates will then add a button to all estates in estate lists, so that visitors can add them to their favorites.
Go to your estate list and add a few estates to your favorites. Then go to the page with the favorite list’s shortcode and they should appear there.
