使用jQuery插件select2 multiselect如何选择一个组及其所有子组，但允许多个子组被选中，当该组未被选中时?下面您将发现一个jsfiddle，它允许选择组，但一次只能选择一个子组。如有任何帮助，我将不胜感激。

HTML代码: 

<input type='hidden' id='select'>

JS代码:

$(function () {
var select2_ary = [];
select2_ary.push(
{id: 'numbers', text: 'numbers',
    children: [
        {id: "numbers", text: "1"},
        {id: "numbers", text: "2"},
        {id: "numbers", text: "3"},
        {id: "numbers", text: "4"},
        {id: "numbers", text: "5"}
    ]
}, 
{id: 'letters', text: 'letters',
    children: [
        {id: "letters", text: "A"},
        {id: "letters", text: "B"},
        {id: "letters", text: "C"},
        {id: "letters", text: "D"},
        {id: "letters", text: "E"}
    ]
}
);
$("#select").select2({
    placeholder: "Select",
    data: select2_ary,
    multiple: true,
    width: "300px"
});
});

你不能有一个以上的选项相同的id，这就是为什么你得到这个行为。
