OBIEE remove the whole portalbanner

Or how how to remove this in one go:

Add a textbox to your dashboard:

Add the following code:
[code]
<script type="text/javascript">
    var tds = document.getElementsByTagName('table');
    for (var td = 0; td < tds.length; td++) {
        if (tds[td].className != 'PortalBanner' && tds[td].className != 'PortalBottomTable' ) {
            continue;
        }
        if (tds[td].className == 'PortalBanner') {
        //alert (tds[td].className);
        var x = tds[td].parentNode;
        //alert (x.className);
        x.removeChild(tds[td]);}
        if (tds[td].className == 'PortalBottomTable') {
        //alert (tds[td].className);
        var x = tds[td].parentNode;
        //alert (x.className);
        x.removeChild(tds[td]);}
        }
</script>
[/code]

Till Next Time

Update:
Stijn showed an much simpler trick by using the GO URL: http://oraclebizint.wordpress.com/2007/11/01/oracle-bi-ee-101332-hiding-banner-in-dashboards-using-go-url/

Update2:
for OBIEE11Gr5 :

The formatting was screwed up replace 'PortalBanner' ==> 'HeaderTopBar'
'PortalBottomTable' ==> 'HeaderSecondBar ' (Including the space)
