Menu Position References Hierarchy

This module allows to render breadcrumbs according to a hierarchy of nodes defined via node reference fields.

Dependencies:

• Menu Position
• References

Example of usage:

1. Create content types with some kind of parent-child relationship, e.g. Category and Product
2. On the Page create a node reference field for the selection of parent Categories
3. Create a new menu position rule and select the parent reference field in the Node Hierarchy tab

Now, if you e.g. have the following hierarchy...

• Category 1
  • Product 1
  • Product 2
• Category 2
  • Product 3

... then your breadcrumbs will look like this for Product 2: [Frontpage] > [Category 1] > [Product 2]
- instead of just [Frontpage] > [Product 2].

Notes:

• The hierarchy can be up to 7 levels deep, i.e. you can have multiple node reference fields on different content types, and the tree will walk through them upwards from the current page.
• If any node in the tree has a menu item, then the remaining hierarchy links will be nested underneith, and respective menu items will be marked as "active".
