=============

我使用 jquery UI 创建了一个嵌套手风琴。

然而，每当单击嵌套的手风琴时，它后面的所有元素都会消失。关于如何保持元素显示的任何建议？

我认为最好通过图片来描述这个问题：

【问题讨论】：

标签： javascript jquery css jquery-ui jquery-ui-accordion

【解决方案1】：

我认为问题出在下面css中的height：

.trackAccordion {
  margin: 50px auto;
  background-color: #2d2d2d;
  height: 790px;    //Check by commenting the height.
  width: 296px;
  border-radius: 5px;
  color: white;
  font-family: 'Helvetica';
  font-weight: bold;
  padding-top: 30px;
  font-size: 1em;
  text-align: center;
  overflow: hidden;
}

谢谢！这就是问题所在！
