<ul> <li/> </ul> structure is required by menu.js. Check to menujs.com.

We create a container div tag with a <ul/> menu items holder. The submenu hierarchy will be placed at the <t:body/> element. It should be nested <li/> <ul/> structure with <a/> for the action for the menu actions

<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd" xmlns:p="tapestry:parameter">
        <style type="text/css">
                /*override/change the css if you want*/
                .menu a.selected  { color: #0079c0; background: red;}
        <div class="menuBar">
                <ul class="menu" id="${menuID}">
