bootstrap---treeview使用方法

1、html部分：

<div id="tree"></div>

2、css设置展开/收缩按钮图片：

.tree_arrows_down:before{
	content:url("../img/down.png");
}

.tree_arrows_right:before{
	content:url("../img/right.png");
}

3、js部分实现：

$('#tree').treeview({
	data: treeData,
	expandIcon: "tree_arrows_right",
	collapseIcon: "tree_arrows_down",
	levels : 3,
	onhoverColor: "#E8E8E8",
	showBorder: false,
	showTags: true,
	highlightSelected: true,
	highlightSearchResults:false,
	selectedBackColor: "#8D9CAA",
}); 

4、数据（treeData）格式：

var treeData =[
	{
		text: "第一中学",
		nodes: [
		{
			text: "高一年级",
			nodes: [
				{
					text: "一班",
					nodes: [
						{
							text: "三组",//

					]
				}
			]
		},
		{
			text: "高二年级",
			nodes: [

					text: "一班",
					nodes: [
