JavaScript/jQuery List - Grouped List
The JavaScript List component can display items as a two-level hierarchy: parent and child items. To group items, set the grouped property to true and ensure the data source defines the hierarchy in one of the following ways.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
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. This demo shows how to use this type of data source.
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.
Grouping Field
The data source can contain a plain list 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.
Group Display Settings
If you need to make the groups collapsible, set the collapsibleGroups to true.
You can also use the groupTemplate property to customize the appearance of group headers.
