Selectively displaying certain items in a list // logic tag in adf

Question

Hi,
I have a tree the children of which can be of two types based on a child property. I want to be able to display only one type of children in a for loop. I could not find an <af: if > kind of tag that will let me check a child property in that i can use to filter in a for loop.
<af:menuBar>
<af:forEach var="subsystem" items="#{menuModelTree.instance}">
<af:menu text="#{subsystem.name}">
<af:forEach var="item" items="#{subsystem.childrenItems}">
????? if item.childProperty == certain type then {do the following } ??????
<af:commandMenuItem text="#{item.name}"
actionListener="#{menuModelBase.displayForm}"
action="#{item.getDestination}"/>
</af:forEach>
</af:menu>
</af:forEach>
</af:menuBar>
Thanks,

User,
JSTL has an if tag, but don't use it!
I could recommend a couple of approaches... if you only want to display one type of children, but a method in your backing bean (subsystem) that would return only the items of interest and use that in your af:forEach loop.
Second possibility would be to loop through everything, but set the"rendered" property of your af:commandMenuItem to "#{item.childProperty == certain type}"
