css - set max-width for select
提问by Patrick
I have a form with a drop down list of venues and a submit button. They are supposed to be on the same line, but since the list of venues is dynamic, it could become too long and push the button down.
我有一个带有场地下拉列表和提交按钮的表单。它们应该在同一条线上，但由于场地列表是动态的，它可能会变得太长并按下按钮。
I was thinking of setting a max-width property to the select, but I'm not clear whether this will work in all browsers. Do you have any suggestions on a workaround?
我正在考虑为 select 设置一个 max-width 属性，但我不清楚这是否适用于所有浏览器。您对解决方法有什么建议吗？
<form action="http://localhost/ci-llmg/index.php/welcome/searchVenueForm" method="post" class="searchform">
<select name="venue">
<option value="0" selected="selected">Select venue...</option>
<option value="1">venue 0</option>
<option value="2">club 1</option>
<option value="3">disco 2</option>
<option value="4">future test venue</option>
</select>
<input type="submit" name="" value="Show venue!" class="submitButton" />
</form>
css:
css：
.searchform select {
max-width: 320px;
}
.searchform input.submitButton {
float: right;
}

If the venues are generated on the server side, you can use your server-side scripting to cut them down to a specific maximum character count.
如果场地是在服务器端生成的，您可以使用服务器端脚本将它们减少到特定的最大字符数。
When using pure CSS I'd also try setting overflow:hidden, both on the selectand the optionelements. Also try setting max-widthon the option element. When it works in all non-IE, you can use the usual scripts to add max-width support for IE.
使用纯 CSS 时，我还会尝试overflow:hidden在select和option元素上设置。还可以尝试max-width在选项元素上设置。当它适用于所有非 IE 时，您可以使用常用脚本为 IE 添加 max-width 支持。

尝试：
fieldset select {
width: auto;
}
