Answer 1

如果我理解正确，你需要两个排序 - 一个用于父母，一个用于孩子，然后孩子应该connectWith父母，你需要一个tolerance财产。

// Sort the parents
$(".sortable").sortable({
    containment: "parent",
    items: "> div",
    handle: ".move",
    tolerance: "pointer",
    cursor: "move",
    opacity: 0.7,
    revert: 300,
    delay: 150,
    dropOnEmpty: true,
    placeholder: "movable-placeholder",
    start: function(e, ui) {
        ui.placeholder.height(ui.helper.outerHeight());
    }
};

// Sort the children
$(".group-items").sortable({
    containment: "parent",
    items: "> div",
    tolerance: "pointer",
    connectWith: '.group-items'
});
