You can check if Select2 operations give and error or not with try..catch. If there is an error thrown, that means that there is not Select2 in the element.

The downside is that this will still output an error in the browser console.

try {
    $(obj).select2("close")
} catch(err) {
    // No Select2 in the element
    $(obj).select2({ width: "455px" });
}
