 The prop accepts an object of type [`GridSlotsComponent`](/x/api/data-grid/data-grid/#slots).
 
 If you wish to pass additional props in a component slot, you can do it using the `slotProps` prop.
-This prop is of type `GridSlotsComponentsProps`.
+This prop is of type `GridSlotsComponentsProps`. Note that if you do and you use typescript, you'll need to cast your custom component so it can fit in the slot type.
 
 As an example, you could override the column menu and pass additional props as below.
 
-```jsx
+```tsx
 <DataGrid
   rows={rows}
   columns={columns}
   slots={{
-    columnMenu: MyCustomColumnMenu,
+    columnMenu: MyCustomColumnMenu as DataGridProps['slots']['columnMenu'],
   }}
   slotProps={{
     columnMenu: { background: 'red', counter: rows.length },
   }}
 />
 ```
 
+If you want to ensure type safety, you can declare your component using the slot props typings:
+
+```tsx
+import { GridSlotProps } from '@mui/x-data-grid';
+
+function MyCustomColumnMenu(
+  props: GridSlotProps['columnMenu'] & { background: string; counter: number },
+) {
+  // ...
+}
+```

 ### Interacting with the data grid
 
 The grid exposes two hooks to help you to access the data grid data while overriding component slots.
