| 11 | +# Resource Grouping Header Templates |
| 12 | + |
| 13 | +You can use the `SchedulerResourceGroupHeaderTemplate` to customize the rendering of the Scheduler resource grouping header cells. This allows you to change the appearance of the content, add custom content or any HTML elements. |
| 14 | + |
| 15 | +The `SchedulerResourceGroupHeaderTemplate`: |
| 16 | +* Is invoked for each resource when the Scheduler is configured to have resources and grouping. |
| 17 | +* Applies in both horizontal and vertical grouping. |
| 18 | +* Can be defined at the root level of the Scheduler and individually for each [Scheduler views]({%slug scheduler-views-overview%}). When configured at the root, the template applies to all views. If a `SchedulerResourceGroupHeaderTemplate` is defined at the view level, it will override the root-level template for that specific view. |
| 19 | + |
| 20 | +The `context` of the template is a `SchedulerResourceGroupHeaderTemplateContext` object that contains: |
| 21 | + |
| 22 | +| Property | Type | Description | |
| 23 | +| --- | --- | --- | |
| 24 | +| `Text` | `string` | The group text. | |
| 25 | +| `Value` | `object` | The resource value.| |
| 26 | +| `Field` | `string` | The field of the resource. | |
