# GroupingColumnsConfig

> _Since v1.7.0_

Grouping-columns config widened to accept Angular component classes for
`groupHeaderRenderer` and per-group `renderer` inside `columnGroups`.

Component instances receive the GroupHeaderRenderParams fields as
inputs (`id`, `label`, `columns`, `firstIndex`, `isImplicit`).

```ts
type GroupingColumnsConfig = Omit<CoreGroupingColumnsConfig, "groupHeaderRenderer" | "columnGroups"> & object
```
