I have a page that I am trying to slide open a layer onthe page. I have pulled some code and am very close, but need some help. The remaining isseues are:

1) when the layer becomes visible, I want the copy on the page to move below it. I think this is just chaning the z-index.
2) I would like the layer to open when the page loads. I can not put this in the BODY tag and tried to open another <script> tag, but could not get it to work.

Thanks for any help.

<html>
<head>
      <script language="javascript" src="../ypSlideOutMenus.js"></script>
      <script language="javascript">
            new ypSlideOutMenu("menu1", "down", 20, 20, 500, 200)

    ypSlideOutMenu.writeCSS();
   
      </script>

      <style type="text/css">
            /* just basic text formatting - nothing special */
            @import "/_common/demo.css";

Hi td234,

1. Yes the z-index controls front-back layering.  When you say below do you mean behind or underneath?

2. try adding code like this:
    window.onload=function() { yourfunction();}

Hope this helps,
Neal.
