Simply remove its child elements which are <option>

Answer 2

function RemoveItems()
{
   var objDrpList = document.getElementById ('theIdOfYourDdl');

   for(i=objDrpList.length-1; i>=0; i--)
   {
      if(objDrpList.options[i].selected)
      {
         objDrpList.options[i] = null;
      }
   }

EDIT:

Darin's answer is actually the way to go. Both work, but less code is better.

Answer 3

document.getElementById('idofselectbox').options.length = 0;
