弹出窗口显示。但是，如果内容太大，则不会显示滚动条。如何在需要时让滚动条始终显示？
答案 0 :(得分：3)
您是否尝试在div上设置样式？
<h:panelGroup layout="block" id="container" style="overflow:scroll"> ... </h:panelGroup>
如果可行，那么最好的方法是定义一个类。
也许您还必须明确定义弹出窗口的大小才能使其正常工作。
更新
最终解决方案是在<h:panelGroup>..</h:panelGroup>内使用<rich:popupPanel>块，而不添加任何其他样式信息。 <rich:popupPanel>已经在其内容周围呈现了一个overflow:auto样式的div，但如果内部只有普通的html代码，则弹出窗口的大小计算似乎会失败。
