<atleap:prepareMenu name= "FrontendMenu " var= "frontendMenu " scope= "request " />
<atleap:iterator items= "${frontendMenu.componentsAsPlainList} " var= "item " scope= "request " statusVar= "status " statusScope= "request ">
<c:set var= "itemId " value= "${item.ident} " />
<c:choose>
<c:when test= "${status.first} ">
<div id= "${frontendMenu.ident} ">
<atleap:iterator items= "${item.components} " var= "item " scope= "request " statusVar= "loopStatus " statusScope= "request ">
<jsp:include page= "/WEB-INF/pages/core/frontendMenuItem.jsp " />
</atleap:iterator>
</div>
</c:when>
<c:otherwise>
<c:set var= "menuClassName " value= "dropDownMenu " />
<c:if test= "${empty item.components} ">
<c:set var= "className " value= "dropDownMenu_empty " />
</c:if>
<div class= "${menuClassName} " id= "${itemId}__childItems " style= "position: absolute; visibility: hidden ">
<atleap:iterator items= "${item.components} " var= "item " scope= "request " statusVar= "loopStatus " statusScope= "request ">
<jsp:include page= "/WEB-INF/pages/core/frontendMenuItem.jsp " />
</atleap:iterator>
</div>
