Detail Template in React TreeGrid component

01 Feb 2023 / 2 minutes to read

The detail template provides additional information about a particular row. By expanding the parent row the child rows are expanded along with their detail template. The detailTemplate property accepts either the template string or HTML element ID.

To use detail template, inject the DetailRow module in the TreeGrid.
