支持搜索：
JS代码， 如果Group不需要勾选，goup不加id就可以了 。如果需要三级，可以在二级的基础上做修改。
代码是当时在google上搜到的。不记得是哪里的了。
var arr = [
{
"text": "Group1",
"id": "001",
"children": [
{
"id": "001-1",
"text": "member1-1",
}
]
},
{
"text": "Group2",
"id": "002",
"children": [
{
"id": "002-1",
"text": "member2-1",
},
{
"id": "002-2",
"text": "member2-2",
}
]
},
{
"text": "Group3",
"id": "003",
"children": [
{
"id": "003-1",
"text": "member3-1",
},
{
"id": "003-2",
"text": "member3-2",
},
{
"id": "003-3",
"text": "member3-3",
}
]
}
]; $(".group-select").select2({
placeholder: "Select group or member",
allowClear:true,
data: arr,
query: function (options){
var selectedIds = options.element.select2('val');
var data = jQuery.extend(true, {}, this.data);
var selectableGroups = $.map(data, function (group) {
var areAllChildrenSelected = true,
parentMatchTerm = false,
anyChildMatchTerm = false;
if (group.text.toLowerCase().indexOf(options.term.toLowerCase()) >= 0) {
parentMatchTerm = true;
}
var i = group.children.length;
while (i--) {
var child = group.children[i];
if (selectedIds.indexOf(child.id) < 0) {
areAllChildrenSelected = false;
}
if (options.term == '' || (child.text.toLowerCase().indexOf(options.term.toLowerCase()) >= 0)) {
anyChildMatchTerm = true;
}
else if (!parentMatchTerm) {
var index = group.children.indexOf(child);
if (index > -1) {
group.children.splice(index, 1);
}
}
}
return (!areAllChildrenSelected && (parentMatchTerm || anyChildMatchTerm)) ? group : null;
});
options.callback({ results: selectableGroups });
