                    <p><span class="initial-space"></span>To prevent group from expanding, the <span style="color:#c60d0d">beforeSelect</span> events is handled. This event is fired just before the <span style="color:#c60d0d">beforeExpand</span> event and it is better for this case. If the group is checked, the cancel field (from event data) is set to false. This cancels any further actions for specified group.</p>
