Question

我在使用我的webapp的前端时遇到了一些问题。有几个问题：

如果时间过长，我需要剪切文字，所以

.suggestion-box-text {white-space：nowrap;溢出：隐藏;
文本溢出：省略号; }

但是我不能在Chrome中使用滚动，只能使用按键。 2.无论我使用什么，Safari都会记住列表中最后选择的项目，下次使用选择时，它会从它开始，而不是从第一个元素开始。

在FireFox中也无法正常工作，当做同样的事情来剪切太长的文本时，滚动仍然有效，但是当我用键移动时，列表不会滚动。

有没有任何已知的方法来解决这个问题？或者只是尝试一下好运，直到找到合适的组合？

最好使用ngOptions指令（它比<option>上的ng-repeat快得多 https://docs.angularjs.org/api/ng/directive/ngOptions
