Pascal France	Tuesday 12 May 2009 7:24:54 am Hi, I have a tree which looks like that: level1 \|---item1 \|----child1 \|----child2 \|----child3 \|---item2 \|----child1 \|----child2 \|---item3 \|----child1 \|----child2 \|----child3 Is there a way to fetch, with a single fetch, each first child of each <i>item</i> nodes ? In fact, I would like to create a menu \| item1 \| item2 \| item3 \| where each item is a link to its first child, and I would like to optimize the number of db queries.

Then with fetch tree function filter only priority = 0. This is just an idea, I didn't do it :) http://www.linkedin.com/in/ivolukac http://www.netgen.hr/eng/blog http://twitter.com/ilukac

Michael Fürst	Thursday 14 May 2009 2:36:20 am Hi, Yeah, you are of course able to fetch only the items on level 1. Here's my example of fetching the menu: {def $menuTop=fetch( content, list, hash( parent_node_id, $indexpage, sort_by, array('priority',true), class_filter_type, include, class_filter_array, array('frontpage','link','contentpage','event_calendar','blog','internal_shortcut','bildergalerie','folder'))) } $indexpage is the node ID of the root node - in your case "level1". Additionally you can use the "depth" parameter to define how many levels shall be fetched. http://ez.no/doc/ez_publish/technical_manual/4_0/reference/modules/content/fetch_functions/list Cheers, Mike
