How to new a custom objectCollection in navigator.virtualInfrastructure

HI,

I want to new a custom object collection in the left hand side in inventory,the image view is below picture.

and in the chassissRack-ui sample,the "listViewId" is "com.vmware.samples.chassis.list",so here How should I do? How should I create the extension points  for "com.vmware.samples.xxxxdomain.list"?

   <!-- Template instance to show all chassis under a Chassis App category -->

    <templateInstance id="com.vmware.samples.lists.samples.allChassis">

       <templateId>vsphere.core.inventorylist.objectCollectionTemplate</templateId>

       <variable name="namespace" value="com.vmware.samples.chassisCollection"/>

       <variable name="title" value="#{chassisLabel}"/>

       <variable name="icon" value="#{chassis}"/>

       <variable name="objectType" value="samples:Chassis"/>

      <variable name="listViewId" value="com.vmware.samples.chassis.list"/>

       <variable name="parentUid" value="com.vmware.samples.chassisAppCategory"/>

    </templateInstance>
