HTML 页面 写法

        <div class="layui-form-item">
            <label class="layui-form-label">部门</label>
            <div class="layui-inline">
                <div id="content">
                    <ul id="zTree" class="zTree"></ul>
                </div>
{{--                <input type="text" name="dept" lay-verify="required" placeholder="请选择部门" autocomplete="off" class="layui-input" readonly="true">--}}
{{--                <div id="treeid" class="demo-input-tree demo-tree-box"></div>--}}

            </div>
        </div>
