Tree Data provides a way to supply the grid with structured hierarchical data.
Enabling Tree Data Copy
To enable Tree Data set the treeData property to true in the grid options, and provide a getDataPath callback to configure the Row Hierarchy. Alternatively, see how to Provide Tree Data.
The example above uses the following configuration to enable Tree Data:
const treeData = true;
const getDataPath = useCallback(data => data.path, []);
<AgGridReact
treeData={treeData}
getDataPath={getDataPath}
/> API Reference Copy
Set to true to enable the Grid to work with Tree Data.
You must also implement the getDataPath(data) callback. |
Callback to be used when working with Tree Data when treeData = true. |
The name of the field to use in a data item to retrieve the array of children nodes of a node when while using treeData=true.
It supports accessing nested fields using the dot notation. |
The name of the field to use in a data item to find the parent node of a node when using treeData=true.
The tree will be constructed via relationships between nodes using this field.
getRowId callback need to be provided as well for this to work.
It supports accessing nested fields using the dot notation. |
Allows specifying the group 'auto column' if you are not happy with the default. If grouping, this column definition is included as the first column in the grid. If not grouping, this column is not included. |
If grouping, set to the number of levels to expand by default, e.g. 0 for none, 1 for first level only, etc. Set to -1 to expand everything. |
(Client-side Row Model only) Allows groups to be open by default. |
Set to true prevent Group Rows from sticking to the top of the grid. |
