        <div id="tab1" title="1" style="padding:5px;">
            <div class="easyui-accordion">
                <div class="subgroup" title="1">
                   <p><input type="checkbox" value=""/><label></label></p>
                </div>
                <div class="subgroup" title="1">
                   <p><input type="checkbox" value=""/><label>^__b class="b_3">test3</label></p>
                </div>
            </div>
        </div>
        <div id="tab2" title="2" style="padding:5px;">
            <div class="easyui-accordion">
                <div class="subgroup" title="1">
                   <p><input type="checkbox" value=""/><label>^__b class="b_1">test1</label></p>
                </div>
                <div class="subgroup" title="1">
                   <p><input type="checkbox" value=""/><label>^__b class="b_2">test2</label></p>
                </div>
            </div>
        </div>
    </div>

JS

$(document).ready(function() {
            $('.easyui-accordion').accordion({
                animate: true,
                fit: true
            });
            $('#easyui-tabs').tabs({
                tabPosition: 'left',
                headerWidth: '80'
            });
