[MSvelander]

I use this.

$(".collapseAll").on('click', function() {
    $('.mjs-nestedSortable-branch').addClass('mjs-nestedSortable-collapsed').removeClass('mjs-nestedSortable-expanded');
    $('.disclose-children').children().removeClass('fa-minus-circle').addClass('fa-plus-circle');
});
$(".expandAll").on('click', function() {
    $('.mjs-nestedSortable-branch').addClass('mjs-nestedSortable-expanded').removeClass('mjs-nestedSortable-collapsed');
    $('.disclose-children').children().removeClass('fa-plus-circle').addClass('fa-minus-circle');
});
