Set an un-selectable default description in a drop-down menu

Updated August 27, 2018

In forms, how do I set an un-selectable default description in a drop-down menu? For e.g. if it is a drop-down for States, 'Select a State' the default option should be un-selectable.

The following sample Javascript can do this.

$(document).ready(function () {
	$('#Field93 option[value="choice 1"]').prop('disabled', true);
});

You'll need the ID of your field (in the example below, it's Field93) and the value of your option, which you can find using your browser's inspection tool:

Thank You! Let me check if this works if the dropdown is dynamically populated from a lookup rule.

Oh, yeah, in that case you might need a different selector for the option.

If I give the Default Value as 'Select a State' as given in the Screenshot and append results to it from the Look up Rule,  the Default Value shows up as the last item in the drop down instead of it being the first item.

Recently upgraded to 10.3 and do  not see the option to select 1 as the Default Value.
