If it's still relevant. I took Apeisa's code from the above-mentioned topic and modified it a bit and it seems to work the way you wanded, Soma

<?php

function treeMenu(Page $page = null, $depth = 1, $id = null) {

           $depth -= 1;

           if(is_null($page)) $page = wire('page');
           if(!is_null($id)) $id = " id='$id'";

           $out = "\n<ul$id>";

           $parents = $page->parents;

           // This is where we get pages we want. You could just say template!=news-item
           foreach($page->children() as $child) {
                   $class = "level-" . count($child->parents);
                   $s = '';
                   if($child->numChildren && $depth > 0 ) {
                           $s = str_replace("\n", "\n		", treeMenu($child, $depth));
                   }

                   $class .= " page-{$child->id}";
                   $class = " class='$class'";
                   $out .= "\n	<li$class>\n		<a$class href='{$child->url}'>{$child->title}</a>$s\n	</li>";
           }
       $out .= "\n</ul>";

       return $out;
}

//parameters: current page, menu depth, ul menu id
$menu = treeMenu($page, 3, "myMenu");

echo $menu;

You shoud pass depth as a second parameter. By default it will output only one level.

Edit: optimized code a bit

I like this code, but i need the "Home" menu to be always included...thanks..please help..

Welcome newbie

I did a small change to the code, so it includes the self page on the tree.

EDIT: the code I posted wasn't working. Using the same code you posted here, just change the end (after the function closes) to this:

$homepage = $pages->get("/");

$menu = treeMenu($homepage, 3, "");

echo "<ul id='myMenu'>";
echo "<li class='level0'><a class='level0' href='{$homepage->url}'>{$homepage->title}</a>";
echo $menu;
echo "</li></ul>";

This is not a very elegant way of doing this. Would be best to change the function. But it works.

Thanks very much diogo...but it doesnt work the way i want it...my point is to include the "Home" menu together with other menus...thanks for your help

[diogo]

I'm not sure if i understand. What do you mean by together? Can you put a scheme of what you want here?

[newbie140]

hi drogo..thanks for discussing with me...

thats what i want..even if i will go to "about" page or other page, the navigation structure will still looks the same...thanks

Sorry to disrupt you discussion. Why not simply use https://github.com/somatonic/MarkupSimpleNavigation ?

[newbie140]

Thank you very much Soma...but i only need to display the treemenu up to the 2nd level only at th homepage page...tnx

[diogo]

I'm still a bit confused with what you need... still, another try:

function treeMenu(Page $page = null, $depth = 1, $id = null) {

   $depth -= 1;

   if(is_null($page)) $page = wire('page');
   if(!is_null($id)) $id = " id='$id'";

   $out = "\n<ul$id>";
   $out .= "\n	 <li class='level-1'>\n			<a  class='level-1' href='{$homepage->url}'>{$homepage->title}</a>\n   </li>"; // added the homepage here					  

   $parents = $page->parents;

   // This is where we get pages we want. You could just say template!=news-item
   foreach($page->children() as $child) {
       $class = "level-" . count($child->parents);
       $s = '';
       if($child->numChildren && $depth > 0 ) {
           $s = str_replace("\n", "\n			  ", treeMenu($child, $depth));
       }

       $class .= " page-{$child->id}";
       $class = " class='$class'";
       $out .= "\n	 <li$class>\n			<a$class href='{$child->url}'>{$child->title}</a>$s\n   </li>";
   }
   $out .= "\n</ul>";

   return $out;
}

$homepage = $pages->get("/");

//parameters: current page, menu depth, ul menu id
$menu = treeMenu($homepage, 2, "myMenu"); // this will make the menu be the same in any page

echo $menu;

Thank you very much Soma...but i only need to display the treemenu up to the 2nd level only at th homepage page...tnx

That's what can be done with this module pretty easily.

if($page->template == "home"){
$options = array(
	'max_levels' => 2,
	'show_root' => true
);

echo $treeMenu->render($options);
}
