+### Batch selection with controlled toolbar
+
+By default, `ToolbarBatchActions` is activated if one or more rows is selected. Clicking "Cancel" will deactivate it.
+
+Use the `active` prop to control the toolbar. Note that it will still activate if one or more rows are selected.
+
+You can also prevent the default "Cancel" behavior in the dispatched `on:cancel` event.
