React Tag Box - Grouped Items

The TagBox component can arrange items into a two-level parent-child hierarchy. To group items, set the grouped property to true.

To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
Backend API

Ensure the data source defines the hierarchy in one of the following ways:

  • Grouping Field
    The data source can contain a plain array of objects with multiple fields. Assign a field to the DataSource's group property to create a hierarchical display. Parent items display unique values from the specified field, and Child items display grouped values. This demo shows how to use this data source type.

  • Hierarchical Data Source Structure
    You can use a dataSource where each entry is an object that contains the key and items fields. The key field specifies the group header (parent), and the items field holds an array of child items. A data source can specify different field names if the data is structured in the same way. In this case, implement the DataSource's map function to create key and items field mappings. Refer to the following help topic for more information: Item Mapping.

This demo also shows how to customize the appearance of group headers (the groupTemplate property) and enable search (the searchEnabled property).
