Re: Some Javascript Adventures

[Sebastian Rose <sebastian_rose@gmx.de>]

If your Sitmap looks like this normaly:


  * Folder 1
    - item 1.1
    - item 1.2
    * folder 1.1
      - file 1.1.1
    * folder 1.2
      - file 1.2.1
  * Folder 2
    - item 2.1
    - item 2.2

It collapses all, but the top folders on startup:


  * Folder 1
  * Folder 2


Each folder can be clicked, to expand and collapse from now on.


To do this with each TOC, just use another CSS selector in the jQuery
code: 



 <!--/*--><![CDATA[/*><!--*/
 $(document).ready(
  function(){
  $("#text-table-of-contents ul").eq(0).find("li").each(

 //      ^--- and here

    function(){if($(this).children().eq(0)){
      $(this).css({cursor: "pointer"});
      $(this).bind(
        "click",
        function(){
          if($(this).children().eq(0).is(":visible")) $
 (this).children().eq(0).slideUp(250);
          else $(this).children().eq(0).slideDown(250);
          return false;});}});
  $("#text-table-of-contents ul").eq(0).find("ul").hide();

 //      ^--- and here

 });


If you use correct styles, you could even create a horizontal menubar
with dropdown menus from this.



Best
