問(wèn)題描述

現(xiàn)在實(shí)現(xiàn)的效果是：

我想下面不要滾動(dòng)條，紅框內(nèi)的完整的顯示在彈出框的右邊，這樣怎么實(shí)現(xiàn)？

類(lèi)似下面：

（這個(gè)是ps的）

下面是我的代碼，需要做怎么樣的修改，就可以實(shí)現(xiàn)上面的要求？謝謝?。?/p>

下面是代碼：html：

<p style='display: block;'> <p onclick='hideSelectEvent()'></p> <ul onclick='selectEvent(this)'><li value='A組' class='group'>A組 <ul class='mem-list active'><li class='mem'>張三</li><li class='mem'>李四</li><li class='mem'>王五</li> </ul></li><li value='B組'>B組</li><li value='C組'>C組</li><li value='D組'>D組</li><li value='E組'>E組</li><li value='D組'>D組</li> </ul></p>

CSS代碼：

問(wèn)題解答

小方塊作為大塊的子元素，父元素position 設(shè)置relative ，子元素為absolute.這樣子元素就可以相對(duì)父元素設(shè)置left偏移值。前提是，父元素overflow 別hidden

使用絕對(duì)布局呀，子級(jí)使用absolute。
