I've managed to create this, it's the height of the page but I'm trying to get it to scroll rather than stretch forever downwards
css for .leftnavdiv\[code\].leftnavdiv { padding-top: 40px; overflow: hidden; z-index: 99; position: fixed; _position:absolute; top: 0px; _top:expression(eval(document.body.scrollTop)); left: 0px; width: 10px; height: 100%; background-color: white; a:link color:#FF0000; a:visited color:#00FF00;}\[/code\]html:\[code\]<div class="leftnavdiv"> <div> <table style="height:100%;"> <tr style="height:100%;"> <td valign="top" style="height:100%;"> <div id="makebtnset" style="height:100%; overflow-y: scroll;"> <?php //code removed ?> </div> </td> \[/code\]
