{

if(document.getElementByName(i).disabled == false)

{

document.getElementByName(i).disabled= true;

}

else

{

document.getElementByName(i).disabled= false;

}

}

id="dropdown1"

and then do:
<i>
</i>function disable(i)
{
if(document.getElementById(i).disabled == false)
{
document.getElementById(i).disabled= true;
}
else
{
document.getElementById(i).disabled= false;
}
}


and make sure that disabled is an attribute of the drop down list.
