It seems that most people find this blog looking for a way to remove the title from a value prompt. So, in an attempt not to disappoint, here it is.

For 8.3+
Name your value prompt, Month for example. Immediately following the prompt add the following HTML item:
var form = getFormWarpRequest();
var MonthList = form._oLstChoicesMonth;
MonthList.remove(0);
MonthList.remove(0);
MonthList.removeAttribute(“hasLabel”);

As this is using underlying Cognos javascript functions it may not be supported in an upgrade. The removeAttribute(“hasLabel”) is important to remember. Normally the value prompt has two rows at the beginning that have no data. The hasLabel attribute tells Cognos not to return a value when either of those two rows are selected.
