    Auto Expand menu list

    Hello everyone,
    Please give me a hand.
    I have a hierarchy list run by HTML, CSS and Javasript. I also have Expand All and Collapse All buttons.

    Everytime the page is loaded, the list displays as a collapsing one. What should I have to have to get the list expanding automatically when the page is loaded?

    Thank you very much for your help.

    Below is the scripts

    HTML code:

    <a href="javascript: openMap();">Expand All</a>&nbsp; |&nbsp; <a href="javascript:closeMap();">Collapse All</a>
    <ul id="sitemap">
    <li><a href="#">First link</a>
    <ul>
    <li><a href="#">First link</a>
    <ul>
    <li><a href="#">First link</a></li>
    <li><a href="#">Second link</a></li>
    <li><a href="#">Third link</a></li>
    <li><a href="#">Fourth link</a></li>
    <li><a href="#">Fifth link</a></li>
    </ul>
    </li>
    </ul>
    </li>
    </ul>


    Below is Javascript file:

    this.sitemapstyler = function(){
    var sitemap = document.getElementById("sitemap")
    if(sitemap){

    this.listItem = function(li){
    if(li.getElementsByTagName("ul").length > 0){
    var ul = li.getElementsByTagName("ul")[0];
    ul.style.display = "none";
    var span = document.createElement("span");
    span.className = "collapsed";
    span.onclick = function(){
    ul.style.display = (ul.style.display == "none") ? "block" : "none";
    this.className = (ul.style.display == "none") ? "collapsed" : "expanded";
    };
    li.onkeydown = function(e){
    var KeyID = (window.event) ? event.keyCode : e.keyCode;
    switch(KeyID){
    case 37: // left arrow key press
    ul.style.display = "none";
    span.className = "collapsed";
    break;
    case 39: // right arrow key press
    ul.style.display = "block";
    span.className = "expanded";
    break;
    }
    };
    li.appendChild(span);
    };
    };

    var items = sitemap.getElementsByTagName("li");
    for(var i=0;i<items.length;i++){
    listItem(items[i]);
    };

    };
    };

    window.onload = sitemapstyler;

    function openMap(){
    var sitemap = document.getElementById("sitemap")
    if(sitemap){

    this.listItem = function(li){
    if(li.getElementsByTagName("ul").length > 0){
    var ul = li.getElementsByTagName("ul")[0];
    ul.style.display = "block";
    var span = document.createElement("span");
    span.className = "expanded";
    span.onclick = function(){
    ul.style.display = (ul.style.display == "none") ? "block" : "none";
    this.className = (ul.style.display == "none") ? "collapsed" : "expanded";
    };
    li.onkeydown = function(e){
    var KeyID = (window.event) ? event.keyCode : e.keyCode;
    switch(KeyID){
    case 37:
    ul.style.display = "none";
    span.className = "collapsed";
    break;
    case 39:
    ul.style.display = "block";
    span.className = "expanded";
    break;
    }
    };
    li.appendChild(span);
    };
    };

    var items = sitemap.getElementsByTagName("li");
    for(var i=0;i<items.length;i++){
    listItem(items[i]);
    };

    };
    };

    function closeMap(){
    var sitemap = document.getElementById("sitemap")
    if(sitemap){

    this.listItem = function(li){
    if(li.getElementsByTagName("ul").length > 0){
    var ul = li.getElementsByTagName("ul")[0];
    ul.style.display = "none";
    var span = document.createElement("span");
    span.className = "collapsed";
    span.onclick = function(){
    ul.style.display = (ul.style.display == "none") ? "block" : "none";
    this.className = (ul.style.display == "none") ? "collapsed" : "expanded";
    };
    li.onkeydown = function(e){
    var KeyID = (window.event) ? event.keyCode : e.keyCode;
    switch(KeyID){
    case 37:
    ul.style.display = "none";
    span.className = "collapsed";
    break;
    case 39:
    ul.style.display = "block";
    span.className = "expanded";
    break;
    }
    };
    li.appendChild(span);
    };
    };

    var items = sitemap.getElementsByTagName("li");
    for(var i=0;i<items.length;i++){
    listItem(items[i]);
    };

    };
    };
