Display children of the actual menu node (Not all the menu tree)
Last modified: November 16, 2006 - 00:51
In our web (http://www.fundacionalzheimur.org/formacion) we use the structure of the menu primary links, but we haven't found an automatic way of present, as in a book, the child nodes when displaying a menú node.
Our solution is including this php snippet in the node.tpl template, just before the content, in a div floating right:
.... <div class="itemtext">
<!-- Expanded Menu for navigation -->
<?php
$mid = menu_get_active_nontask_item();
$active = menu_get_item($mid);
// this is a top-level link in your primary links
if($active['pid'] == variable_get('menu_primary_menu', 0)){
$output.= theme('menu_tree',$mid);
print('<div id="menubox"><h2>navigate</h2>');
print $output;
print('</div>');
}
?>
<!-- end of menu -->
<?php print $content?>
</div> .....The CSS would be:
#menubox {
display: block;
float:right;
width: 35%;
margin-left: 18px;
margin-bottom: 18px;
padding-bottom: 5px;
background: #fff url(images/Fondo_Logo_menu.jpg) no-repeat bottom right;
}
#menubox h2 {
background: #fff url(images/block-quote_left.gif) no-repeat top left;
color: #6A0D22;
padding: 7px 7px 7px 37px;
margin-bottom: 2px;
line-height: 0.6em;
}
See module submenutree
While surfing, I came across this (apparently) old page. If you have a Drupal 5.x site, you may be interested in submenutree.
Submenutree drupal 6
Also available for Drupal 6
In Drupal 6
I don't know if it's exceedingly complicate, but this is what worked for me to display inside a page just the children (and their childrens and so on) of the current menu item.
<?php
$item = menu_get_item();
$tree = menu_tree_page_data('primary-links');
list($key, $curr) = each($tree);
while ($curr) {
// Terminate the loop when we find the current path in the active trail.
if ($curr['link']['href'] == $item['href']) {
$tree = $curr['below'];
$curr = FALSE;
}
else {
// Add the link if it's in the active trail, then move to the link below.
if ($curr['link']['in_active_trail']) {
$tree = $curr['below'] ? $curr['below'] : array();
}
list($key, $curr) = each($tree);
}
}
$menuhtml = theme_menu_tree(menu_tree_output($tree));
print $menuhtml;
?>
In Drupal 6
where your code be added
modifcation w/ third-level support
<?php
foreach( $tree as $k => $v ) {
$thirdLevel = array(); // this will hold third levels as we iterate the tree
list($key, $curr) = each($v); // capture current node in tree
while ($curr) {
if ( is_array($curr['below']) ) { // if this node has children
array_push( $thirdLevel, $curr['below']); // push them into thirdLevel
unset( $tree[$key]['below'] ); // unset the child nodes in main tree, so no reuse
if ( count($thirdLevel) > 0 ) { // if there are any children
foreach( $thirdLevel as $key => $val ) { // we pushed multiples, right
$links = theme_menu_tree(menu_tree_output($val)); // these get syled within a ul class=menu... good enough hook for me!
$output .= $links;
}
}
$curr = FALSE;
}
else { // well, no children here, so these are second level links
list($key, $curr) = each($tree); // capture node
foreach( $curr as $k => $v ) {
if ( is_array($v) && $v['href'] ) { // they aren't all links!
$output .= '<a href="/'.$v['href'].'">'.$v['title'].'</a>';
}
}
}
}
}
?>
oh
and it be added in a custom function you call
What custom method?
You mentioned custom method. Would you be able to provide the entire flow (template.php, page.tpl.php)?
Thank you!
Menu block module
This very flexible module may also do the trick: http://drupal.org/project/menu_block
