The S3HierarchyWidget class provides a drop-down options widget with a folder-tree style menu for hierarchical lookup fields.
It is used for both CRUD form widgets (both directly and inline link), as well as a filter widget (S3HierarchyFilter).
Python Widget Class
The S3HierarchyWidget (modules/s3/s3widgets.py) uses the S3Hierarchy toolkit to extract hierarchy information for the lookup table and to render it as a nested unsorted list (<ul>), then instantiates a hierarchicalopts widget (static/scripts/s3/s3.jquery.ui.hierarchicalopts.js).
It is currently used in 3 different use-cases:
- S3HierarchyWidget (directly as CRUD widget)
- S3HierarchyFilter (filter widget)
- S3SQLInlineLink (inline-widget to create link table entries to a hierarchical lookup table)
See S3/S3Hierarchy how to configure the hierarchy for the lookup table.
Currently, the S3HierarchyWidget does not yet support custom hierarchy data.
