Hi everyone, are there any way to create "optgroup" inside from a "select" in the form?
Any could show me an example, please
I tried of this way but didn't work
var selects = document.querySelectorAll("select");
for (var i = 0; i < selects.length; i++ ){
selects[i].appendChild(document.createElement("optgroup"));
}
and another example that I tried is this:
var foundin = $('#pruebaoptgroup options:contains("optgroup-")');
$.each(foundin, function(value){
var updated = $(this).val().replace('optgroup-','');
$(this).nextUntil('option:contains("endoptgroup")').wrapAll('<optgroup label="'+updated+'"></optgroup>');
});
$('#pruebaoptgroup options:contains("optgroup-")').remove();
$('#pruebaoptgroup options:contains("endoptgroup")').remove();
