Matthew Carroll	Saturday 24 June 2006 11:02:18 am I don't think that you can use an attribute filter to do that. An extended_attribute_filter, maybe, but much easier, I think, would be to fetch all the nodes then 'filter' them in the template, using children_count. Assuming you've fetched the array of nodes as $list, something like: {foreach $list as $listitem} {if ne( $listitem.children_count, 0 )} ...... {/if} {/foreach} http://ez.no/doc/ez_publish/technical_manual/3_8/reference/objects/ezcontentobjecttreenode Hope that helps...

Milad P	Sunday 25 June 2006 7:36:49 am how do you limit the loop? Eq. After that i have fetched and checked with children_count that the objecvt have a child, then i only want it to show say top three objects. How do i limit it? //Milad
