- Select an InputButton component from the drop-down list and click Add to add it to the panel.
- In the Members pane, select InputGroupHeader and then set its Collapsible property to True.

- Click OK to close the C1InputPanel Item Collection Editor. Observe that there is a node present on the InputGroupHeader component.
