我有一个大约 30 个项目的下拉列表，我只想显示 8 个项目，然后下拉列表应该滚动。我在VS2010中使用MVC2

<%= Html.DropDownListFor(d => d.Thing.ThingID, Model.Things, new { style = "width: 200px", rows = 10 })%>

I have a drop down list of around 30 items and I want to only show 8 items and then the drop down should scroll. I'm using MVC2 in VS2010

<%= Html.DropDownListFor(d => d.Thing.ThingID, Model.Things, new { style = "width: 200px", rows = 10 })%>

您是否尝试过 size 而不是 rows ？

<%= Html.DropDownListFor(d => d.Thing.ThingID, Model.Things, new { style = "width: 200px", size = 10 })%>

根据w3 http://www.w3schools.com/tags/att_select_size.asp size 是您要查找的属性。

阅读您的回复后，答案似乎是它独立于操作系统/浏览器，并且无法通过 html 进行控制。您可以做的是使用纯 HTML 版本覆盖选择框。您可以在此网站上执行类似的操作： http://mypocket-technologies.com/jquery/SelectBoxPlugin/ 但是，它可能会导致其他问题，并且看起来不像标准列表框。

have you tried size instead of rows?

<%= Html.DropDownListFor(d => d.Thing.ThingID, Model.Things, new { style = "width: 200px", size = 10 })%>

According to the w3 http://www.w3schools.com/tags/att_select_size.asp size is the attribute you're looking for.

After reading your response the answer appears to be that it's operating system/browser independent and not possible to control through html. What you could do is override the select box with an HTML only version. You could do something like on this site: http://mypocket-technologies.com/jquery/SelectBoxPlugin/ However it may cause other problems and won't look like a standard list box.
