Is there a way to remove optgroup without breaking the code?

All I was trying to do was edit some old code where I made a bunch of options, but now I would like to remove it. I can't just do it with css because it uses the plugin of choice.

function flavorChooser (title, item) {
var title = 'hidden';
var optgroup = jQuery('<optgroup display="' + title + '"/>');


jQuery.each(item, function(sub_title, sub_item) {
    if (typeof sub_item[0] !== "undefined") {
        var opt = jQuery('<option value="' + sub_item[0] + '" data-store-locator-value="' + sub_item[0] + '">' + sub_title + '</option>');
        optgroup.prepend(opt);
    }
});
// console.log('chozen ');
// jQuery('.chzn-container .chzn-results .group-result').css('display', 'none');
return optgroup;

This allows you to remove all children of a optgroup

given element select

:

Markup:

<select id="mySelect">
    <optgroup label="MyGroup"></optgroup>
    <option>Option</option>
    <option>Option</option>
    <option>Option</option>
    <option>Option</option>
    <optgroup label="MyGroup2"></optgroup>
    <option>Option</option>
    <option>Option</option>
    <option>Option</option>
</select>


JQuery

 $(function () {
        $("#mySelect").children().remove("optgroup");
    });
