Widgets
If you chose to create widgets for your entities, you will be able to add your entity widgets in the cms pages.
For the non tree entities you have 2 widgets available. A link widget and a view widget.
The link widget will display a link to the selected entity.
For view entity, you will see some html markup with the attribute values you selected to include in the widget.
For the tree entities you have one additional widget called 'Subtree'. This allows you to select one of the entity instances and it will print a tree like structure with all the child entities of that selected entity.
Very useful if you want to include sidebar menus in certain pages.
