// @see https://select2.github.io/examples.html#data-ajax
// copy Bootstrap validation states to Select2 dropdown
//
// add .has-waring, .has-error, .has-succes to the Select2 dropdown
// (was #select2-drop in Select2 v3.x, in Select2 v4 can be selected via
// body > .select2-container) if _any_ of the opened Select2's parents
// has one of these forementioned classes (YUCK! ;-))
$(".select2-single, .select2-multiple, .select2-allow-clear, .js-data-example-ajax").on("select2:open", function() {
if ($(this).parents("[class*='has-']").length) {
var classNames = $(this).parents("[class*='has-']")[0].className.split(/\s+/);
for (var i = 0; i < classNames.length; ++i) {
if (classNames[i].match("has-")) {
$("body > .select2-container").addClass(classNames[i]);
}
}
}
});
</script>
</div>
</body>
</html>
Step3: don’t forget to add anchor.min.js and select2.full.js file
that’s it.
