如何限制html.dropdownlist中显示的项目数量？
我的网页上有一个 html.dropdownlist ，如下所示：
<%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%>
我正在用大约 80 个项目填充下拉列表。
问题是，当我单击下拉菜单时，项目列表将从屏幕顶部呈现到屏幕底部。
如何设置下拉列表，使其在单击下拉菜单时最多只显示 20 个项目（即用户需要向下滚动才能看到第 21 - 80 项）？
我预计（！）会有一个 html.dropdownlist 属性来控制显示项目的数量，这将允许类似以下内容的操作，例如：
<% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %>
从我在 msdn 网站上所做的研究来看，它似乎没有这样的属性，并且每个浏览器都有自己的下拉列表中显示多少项的规则（？）。
我使用的是IE6和IE7。
I have a html.dropdownlist on my webpage as follows:
<%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%>
I am populating the dropdown with ~80 items.
The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen.
How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)?
I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.:
<% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %>
From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?).
I am using IE6 and IE7.

FlexBox 允许您“分页”行。
