HTML：<p class="p">基础</p>
<div class="show">
<ul>
<li><a href="#">aa</a></li>
<li><a href="#">ss</a></li>
<li><a href="#">dd</a></li>
<li><a href="#">ff</a></li>
<li><a href="#">gg</a></li>
</ul>
</div>
css:
.show{
display:none
}
js:
var isClick=true
$(".p").click(function(){
if(isClick){
$(".show").css("display","block")
isClick=false
}else{
$(".show").css("display","none")
isClick=true
}
})
思路，
要显示的内容用一个div包住，当你点击基础的时候，div显示，再点击时div隐藏
