Breadcrumbs¶
Breadcrumbs are a Drupal concept. They provide a hierarchical path of links to "ancestors" of the current content item.
Islandora Breadcrumbs¶
Islandora provides a module, "Islandora Breadcrumbs" (a submodule
of the Islandora module) that creates breadcrumbs based on the value
of configured reference fields (by default, field_member_of).
To use Islandora Breadcrumbs, simply enable
the module. Islandora breadcrumbs will apply to nodes that have
the configured Entity Reference fields.
There are a few configuration options for this module, accessible at
Manage > Configuration > Islandora > Breadcrumbs
Settings (/admin/config/islandora/breadcrumbs). These include:
- Maximum number of ancestor breadcrumbs - an optional feature to stop adding "ancestor" links after a certain number
- Include the current node in the breadcrumbs?
- Entity Reference fields to follow - if you're using other fields to refer to parents, you can add them here.
Troubleshooting Breadcrumbs¶
Breadcrumbs are cached, so if you aren't seeing the results that you expect, try clearing the Drupal cache.
