Ant Design Collapse components cannot be used

  <Collapse
    activeKey={this.state.activeKey}
    onChange={this.onHandleChange}
  >
    {this.displayCollapse(data)}
  </Collapse>

when using the activeKey component of the Collapse component, click Panel , as shown in the code. Is there a way to use the activeKey function and click Panel to expand?
