Different Context menu on each node of tree - jsf

Question

In my JSF project I want to display different context menu on every node of tree based on some conditions (To be precise some permissions)
Present according to my xhtml, I have binded context menu with the tree so I am getting same menu on every node of the tree.
Here is the code:
<p:contextMenu for="TreeID">
<p:menuitem value="Create" update=":centerPanel" actionListener="#{someBean.createPrivilege}" onstart="statusDialog.show();"
oncomplete="statusDialog.hide();" />
<p:menuitem value="Edit" update=":commonDialog :centerPanel" actionListener="#{someBean.editPrivilege}"
onstart="statusDialog.show();" oncomplete="statusDialog.hide();" />
<p:menuitem value="Delete" onstart="delPrivilegeConfirmDialog.show();" />
</p:contextMenu>
<p:scrollPanel mode="native" styleClass="scroll-panel">
<p:tree id="TreeID" value="root" var="node" selectionMode="single"
selection="#{someBean.selectedNode}" dynamic="true">
<p:ajax listener="#{someBean.onNodeSelect}" update=":centerPanel" event="select" onstart="statusDialog.show();"
oncomplete="statusDialog.hide();" />
<p:treeNode id="someID">
<h:outputText value="#{node}" id="lblNode" />
</p:treeNode>
</p:tree>
</p:scrollPanel>
But according to my requirement I want different context menu on every node, basically I have 3 options in my context menu like Create, Edit , Delete.. then I need to hide 1 or 2 option on every node based on certain conditions.
How would I do that?
Thanks in advance.

Assuming that you are using PrimeFaces, recent versions provide the option to set different context menus for different node types using the "nodeType" attribute:
<p:contextMenu for="TreeID" nodeType="type1">
<p:menuitem value="Create" update=":centerPanel" actionListener="#{someBean.createPrivilege}" onstart="statusDialog.show();"
oncomplete="statusDialog.hide();" />
<p:menuitem value="Edit" update=":commonDialog :centerPanel" actionListener="#{someBean.editPrivilege}"
onstart="statusDialog.show();" oncomplete="statusDialog.hide();" />
<p:menuitem value="Delete" onstart="delPrivilegeConfirmDialog.show();" />
</p:contextMenu>
<p:contextMenu for="TreeID" nodeType="type2">
<!-- Other menu items -->
</p:contextMenu>
<p:scrollPanel mode="native" styleClass="scroll-panel">
<p:tree id="TreeID" value="root" var="node" selectionMode="single"
selection="#{someBean.selectedNode}" dynamic="true">
<p:ajax listener="#{someBean.onNodeSelect}" update=":centerPanel" event="select" onstart="statusDialog.show();"
oncomplete="statusDialog.hide();" />
<p:treeNode id="someID" type="type1">
<h:outputText value="#{node}" id="lblNode" />
</p:treeNode>
<p:treeNode id="someID" type="type2">
<h:outputText value="#{node}" id="lblNode" />
</p:treeNode>
</p:tree>
</p:scrollPanel>
Just keep in mind that you need to set the node type for all nodes generated by the model:
TreeNode x = new DefaultTreeNode("type1", data, parent);
