Menu
I have a select with several options and I try to make some of the options unselectable programmatically. For instance, my code is :
<select>
<option value="1">Value 1</option>
<option value="2">Value 2</option>
<option value="3">Value 3</option>
</select>
<script>
$('select').selectize();
</script>
My question is: how can I make to get option "2" disabled (i.e. not displaying and not selectable) programmatically? -- I tried this code...
$('select')[0].selectize.$dropdown_content.find('[data-value="2"]').removeAttr('data-selectable');
... but it does not work (when I inspect the DOM I see that option "2" has no 'data-selectable' attribute, but it still renders and is selectable...).
Am I wrong here? And if so: what is the proper way to make an option unselectable (I can't find it anywhere in the doc)?
(I created a jsFiddle here: http://jsfiddle.net/j8YUA/3/)

You can use the disabledField setting to make a selectize option "unselectable" programmatically when rendering the options. You can also make an option "unselectable" after the fact using the updateOption method (or you can simply remove the option using the removeOption method) For example:
const options = [
{name: 'Option 1', disable: false},
{name: 'Option 2', disable: true}
];
const sel = $('#select1').selectize({
options: options,
valueField: 'name',
labelField: 'name',
searchField: ['name'],
disabledField: 'disable'
});
$('#button1').click(() => {
sel[0].selectize.updateOption('Option 1', {name: 'Option 1', disable: true});
});
$('#button2').click(() => {
sel[0].selectize.removeOption('Option 2');

</html>Seems like disabledField is not implemented. alternatively, you can add a disabled property to the option you want to disable, and do the following:
$('#control').selectize({
render: {
option: function(item, escape) {
if (item.disabled) {
return '<div style="pointer-events: none; color: #aaa;">' + escape(item.label) + '</div>';
}
return '<div>' + escape(item.label) + '</div>';
}
}
});
