Row Details (Angular)

Sometimes rows are bound to data objects that contain more information than would fit easily on FlexGrid. In these scenarios, you may want to use the FlexGridDetailProvider class that is included with the wijmo.grid.detail module. The FlexGridDetailProvider extends the FlexGrid by adding collapse/expand buttons to row headers, and a createDetailCell method you can use to provide additional details about an item.

This example uses Angular.
