Sub of sub page link not appear

[14年前 に Andri Novian によって更新されました。]

I use liferay.5.2.3 with tomcat 6 bundling.
First i create page and then i create a children from page and that's no problem with page menu link, but if i create children from a children page this link menu not appears except in "Site map" portlet this all tree link show as i supposed to do.

the question is how to create a second,third,etc. level tree menu appears in liferay menu

from navigation.vm

#foreach ($nav_item in $nav_items)
##level one
<a href="$nav_item.getURL()" $nav_item.gettarget()>
                    <span>$nav_item.icon() $htmlUtil.escape($nav_item.getName())</span>
                </a>
#if ($nav_item.hasChildren())
##level 2
#foreach ($nav_child in $nav_item.getChildren())

 <a href="$nav_child.getURL()" $nav_child.gettarget()>$nav_child.getName()</a>
#end

#end
##end level 2
#end
##end level one

same way you can go to any level

Hi Iulian Vieru,
Thanx for your reply. But that is limited to only 1 step, since nav_item is for main menu and nav_child is for drop down items. How would we go with 2nd level(sub items of drop down). I tried with adding another loop with nav_sub_child in place of nav_child. But thats not coming in right direction. If you have any example code for the next level please post it once,

Thanks in advance,

The direction you took is the correct one. A loop trough the children of the what you call drop-down items. First is best to understand that these velocity variables are in fact references to java objects, so $nav_item references to a com.liferay.portal.model.Layout instance. So, to get a list of all children of $nav_item, we do it same way as for the Layout object, using getChildren() method.
in java we would do something like this :

Layout parentLayout;
.....

List<layout> childrenLayouts=parentLayout.getChildren();</layout>

Same thing in velocity:

$childrenLayouts=$parentLayout.getChildren()

So, what you need to do is to get the children of the parent item up to whatever level suits your requests. Here is an update to the example i gave above, where you get the next level:

#foreach ($nav_item in $nav_items)
        ##level one
        <a href="$nav_item.getURL()" $nav_item.gettarget()>
            <br>level 1 <span>$nav_item.icon() $htmlUtil.escape($nav_item.getName())</span>
        </a>
            #if ($nav_item.hasChildren())
            ##level 2
            #foreach ($nav_child in $nav_item.getChildren())

                <br>--level2<a href="$nav_child.getURL()" $nav_child.gettarget()>$nav_child.getName()</a>
                 #if ($nav_child.hasChildren())
                     ##level 3
                     #foreach($nav_child3 in $nav_child.getChildren())
                        <br>----level3<a href="$nav_child3.getURL()" $nav_child3.gettarget()>$nav_child3.getName()</a>
                     #end

                 #end
            #end

            #end
        ##end level 2
        #end
