The many-to-many page is a useful tool for editing certain types of relationships. It can be used as a specialized replacement of a CRUD page in some scenarios.

Visually, the many-to-many action appears as a list of checkboxes representing entries in the relationship. Optionally, with certain configuration setups, both sides of the relationship can be open and, in that case, an additional selection box is shown. Selecting a value in the box will show the related values as checkboxes. Alternatively, one side of the relationship is fixed and the selection box does not appear. See the configuration page for more information.
