jQuery ui Autocomplete控件下拉列表高度默认是自适应的，有多少数据就会加载出来多少行。以下是给下拉列表设置一个默认高度并添加滚动条的解决办法。

在样式里添加以下代码

.ui-autocomplete {    max-height: 150px; //默认最大高度150像素    overflow-y: auto; //添加滚动条    /* prevent horizontal scrollbar */    overflow-x: hidden;  }  /* IE 6 doesn't support max-height   * we use height instead, but this forces the menu to always be this tall   */  * html .ui-autocomplete {    height: 150px; //解决IE6下不识别max-height  }
