How to adjust Select drop-down height

htmlhtml-select

提问by Matt Canty

I've looking round the internet for a solution to this and everyone is talking about different things or just saying does size="x"help? I've made a Plunk to illustrate my issue. On my screen I can see up to item 20 when I click the drop down. I'd like to be able to set this to show more, or at least have some control.

我环顾互联网为解决这一点,大家都在谈论不同的事情或只是说大小=“X”的帮助?我做了一个 Plunk 来说明我的问题。在我的屏幕上,当我单击下拉菜单时,最多可以看到第 20 项。我希望能够将其设置为显示更多,或者至少有一些控制权。
