Hi all!

I'm looping through a list of folders to crate a javascript/css menu structure and I would need to know how to establish wether ornot those folders are empty.

Is there a attribute for this? Or a fuction? Or some other magic way?

Cheers

Fetch the children as count and then do an section show on the number of children... Pseudo code:

{let number_children=fetch(content,count,hash(parent_node_id,$node_id))}
{section show $number_children.nq(0)}
do your work on the children
{/section}
{/let}

My syntax is probably wrong, do some search on EZ to find the correct one.

Cheers

Felix,

{let children=fetch(content,list,hash(parent_node_id,$node.node_id))}
    {section show=$children loop=$children}
        {$:item.name}
    {section-else}
        You don`t have any children
    {/section}
{/let}

You can use {section} as "If" instructions.

Even easier if you have already fetched the node:

$node.children_count
