<script type="text/javascript" src="/html/js/liferay/dockbar.js"></script>  <portlet:renderurl var="editlayouturl" windowstate="<%= liferaywindowstate.exclusive.tostring() %>">                 <portlet:param name="struts_action" value="/dockbar/edit_layout_panel" />                 <portlet:param name="closeredirect" value="<%= portalutil.getlayouturl(layout, themedisplay) %>" />                 <portlet:param name="groupid" value="<%= string.valueof(scopegroupid) %>" />                 <portlet:param name="selplid" value="<%= string.valueof(plid) %>" />             </portlet:renderurl>  <aui:nav-item anchorid="editlayoutpanel" cssclass="page-edit-controls" data-panelurl="<%= editlayouturl %>" href="javascript:;" iconcssclass="icon-edit" label="edit" /> <aui:script position="inline" use="liferay-dockbar">     liferay.dockbar.init('#<portlet:namespace />dockbar');      var customizablecolumns = a.all('.portlet-column-content.customizable');      if (customizablecolumns.size() > 0) {         customizablecolumns.get('parentnode').addclass('customizable');     } </aui:script> 

you need register panel in dockbar this:

<aui:script use="liferay-dockbar">     liferay.dockbar.dockbar_panels.mypanel = {         css: 'lfr-has-mypanel',         id: 'mypanel',         node: null,         showfn: a.bind(liferay.dockbar._showpanel, liferay.dockbar),         tpl: '<div class="lfr-add-panel lfr-admin-panel" id="{0}" />'     }; </aui:script>
