大致思路
左侧：菜单，给每个菜单设置id和onclick点击事件，onclick事件触发的函数假设写为display()
右侧：写个固定样式的div，id假设设置为board。
如果你的菜单内容在服务器
display()的实现如下
function display(){$.ajax({
type: "POST",
url: 菜单所请求的内容地址,
data: this.id等等相关的请求标志,
success: funtion(data){$('board').html(data)},//返回数据填充
dataType: dataType})
}
如果菜单内容写死在页面内
那么右侧：写和菜单数一样多的div，把所有的display属性设置为none
同时display()的实现如下
function display(){$('#'+$(this).attr('rel')).style.display='block'
}
以上，伪代码，仅供参考
