Disable an option using extra attribute from server

[sabin2hats]

Is there any way to make an option disabled based on another field value from server , for example now we have id, text field returned from server , can I return an additional parametr as is_freeze so based on thats value option gets disabled.

There is no built-in way to do this, however, if you take a look at the way I build up the options:
https://github.com/ksykulev/chosen-ajax-addition/blob/master/chosen.ajaxaddition.jquery.js#L112-L128

			if (!inputEmptied) {
				if ($.isArray(items)) {
					//array of kv pairs [{id:'', text:''}...]
					$.each(items, function (i, opt) {
						if (typeof valuesHash[opt.id] === 'undefined') {
							$('<option value="' + opt.id + '">' + opt.text + '</option>').appendTo(select);
						}
					});
				} else {
					//hash of kv pairs {'id':'text'...}
					$.each(items, function (value, text) {
						if (typeof valuesHash[value] === 'undefined') {
							$('<option value="' + value + '">' + text + '</option>').appendTo(select);
						}
					});
				}
			}

you should be able to modify the code to use an additional parameter such as is_freeze (assuming it is a boolean..)

Something like this..

			if (!inputEmptied) {
				if ($.isArray(items)) {
					//array of kv pairs [{id:'', text:''}...]
					$.each(items, function (i, opt) {
                                                let disabledFlag = opt.is_freeze ?  'disabled' : '';
						if (typeof valuesHash[opt.id] === 'undefined') {
							$('<option ' + disabledFlag + ' value="' + opt.id + '">' + opt.text + '</option>').appendTo(select);
						}
					});
				} else {
					//hash of kv pairs {'id':'text'...}
					$.each(items, function (value, text) {
                                                let disabledFlag = opt.is_freeze ?  'disabled' : '';
						if (typeof valuesHash[value] === 'undefined') {
							$('<option ' + disabledFlag + ' value="' + value + '">' + text + '</option>').appendTo(select);
						}
					});
				}
			}

I don't really modify the response from the server, so as long as the is_freeze value is returned alongside the id and text fields, it will be available for reference when building the options up.

Also, a word for caution, the original library that this project extends is deprecated (https://github.com/harvesthq/chosen) and I have not worked on this project for a pretty long time, so definitely use it carefully.
