!!NEW!! Expandable Taxonomy tree in new block

Hi there!

I am new to Drupal, but have spent the day installing and messing around.

I have 3 content sites that I would like to consolidate into one drupal site. Each site has several subcategories, so for lack of better knowledge, I thought the easiest way to do it in Drupal is to create 4 categories (aka "vocabulary") and underneath each one the subcategories (aka "terms").

Then I wanted to have them displayed in their own box as headers ("vocabulary") only, which would then upon click on the header dynamically (via Javascript) open the "terms" underneath, each term linked to the actual subsection, and close it again upon another click on the header - a toggle, so to say.

It took me a while, but now it's working nicely, and I'd like to share the results with you. If you think it's not so clean or there is a better way, please let me know. I'm keen to learn. :)

Instructions:

1. Save this as menu-builder.inc in your /includes directory

   
   <?php
   
   $js="
   
   <SCRIPT LANGUAGE=\"JavaScript\"><!--
   function ShowHide(divId, divId2, divId3) {
   	var id = document.getElementById(divId); 
   	var id2 = document.getElementById(divId2); 
   	var id3 = document.getElementById(divId3);
   
   	if (id.style.display == \"none\") {
   		eval(\"id.style.display = 'block'\"); 
   		eval(\"id2.style.display = 'none'\"); 
   		eval(\"id3.style.display = 'block'\");
   	}
   	else {
   		eval(\"id.style.display = 'none'\"); 
   		eval(\"id2.style.display = 'block'\"); 
   		eval(\"id3.style.display = 'none'\");
   	}
   }
   
   //-->
   </script>
   
   ";
   
   $group="";
   $vid=0;
   $id=1;
   $get_tax="
   SELECT v.name AS name, t.tid AS tid, t.name AS item 
     FROM  vocabulary AS v 
     LEFT JOIN term_data AS t ON v.vid=t.vid 
     ORDER BY v.name, t.item";
   $result=mysql_query($get_tax);
   while($row=mysql_fetch_object($result)) {
   
   if($group!="" && $group!=$row->name)  {
   $cat="</div>\n";
   $cat.="</div>\n\n";
   $id++;
   $list.=$cat;
   }
   
   if($group!=$row->name) {
   $group=$row->name;
   $cat="<div id=\"content-block\"> 
   <a href=\"javascript:ShowHide('ID".$id."', 'ID".$id."_m', 'ID".$id."_p', 'ID".$id."_t');\"><b>";
   $cat.=$row->name;
   $cat.="</b></a>\n";
   $cat.="<div id=\"ID".$id."\" style=\"display:none;\">\n";
   $list.=$cat;
   }
   $list.="<li class=\"leaf\">
   <a href=\"?q=taxonomy/page/or/".$row->tid."\">".$row->item."</a>\n";
   
   }
   $cat="</div>\n";
   $cat.="</div>\n";
   $list.=$cat;
   $construct_menu=$js.$list;
   
   mysql_free_result($result);
   
   ?>
   
   

2. In your custom box edit dialog, enter:

   include('./includes/menu-builder.inc');
   return $construct_menu;
   

3. Set it from HTML to PHP
   
4. Save it.
   
5. Activate your custom box and place it wherever you like.
   

What I haven't yet figured out is how to get Drupal to display the taxonomy header and their respective terms (and even the content underneath) as content pages. Example: Tax: Marketing; Term:CRM; Content:Blah Blah So if you click on Marketing, you will see the term CRM, and the content Blah Blah in hierarchical order. Same for all other vocabulary, terms and content. Any ideas?

PS: There isn't a working example of it yet for you to check, but if you have a taxonomy tree, you can try this right away. A screenshot can be found here . Feedback welcome.
