in menu select

[LanKing]

Editing of nested menus became hell: http://joxi.ru/brRKqyIQ0EKDm1
I am just started to explore Laravel and used your solution as admin panel (Cool-Cool-Cool).

Maybe it will be good to add the next js:

$(document).ready(function() {
    $('.select2-hidden-accessible').select2({
        escapeMarkup: function (text) { return text; }
    });
});
