How to make in "DropDown" a single option value disabled (visible but non active)

I would like to ask You, if it is possible (in V5) in "DropDown" to make a single option value disabled, visible but non active and color it by different color, for example active option value by "green" and non active by "red".

Many thanks for Your answer.

Hi Weisgerber,

The only way to do this is using a custom JavaScript in the form load event.

Many thanks for Your answer, but I don´t understand very well. If I choose in ChronoForm functions "Events", there is Basic options, but no choice for "Custom JavaScript" isn´t there. And If I choose "Edit Elements Settings", there in "Events" tab and than "Validation" tab, there is only "Custom Funciton", no "Custom JavaScript". So, can You help me to tell the procedure step by step in ChronoForm?

Many thanks for Your other answer.

Hi Jan,

If I understand correctly you want this to happen when the form loads - so it is not a question about validation. You can add Custom JavaScript using the Load JavaScript action in the form Setup tab.

Hi,

In a "Custom JavaScript" action you can do this:

jQuery(document).ready(function($){
$('option[value="xyz"]').prop("disabled", true);
});
