click event to trigger drop down list

click event to trigger drop down list

I'm using absolute positioning to place my form labels inside my form input and select fields and I'm able to show/hide the label based on focus() and onblur() events, however, I have some undesired effects with the drop down select boxes where if you click on the label portion, the label disappears appropriately but the options are not revealed until you click it again.  Is there a way via jquery to force the "drop down" event on click of the label element?

I've tried $('#selectID').attr("disabled", false); and  $('#selectID').prop("disabled", false); without luck.
