HTML select drop-down with an input field
提问by jesal
How can I implement a select-style drop down menu in HTML with an option that is a text input?
如何使用文本输入选项在 HTML 中实现选择样式的下拉菜单?
The idea being that someone can either select from a list of predefined options, or input their own option.
这个想法是有人可以从预定义选项列表中进行选择,或者输入他们自己的选项。

You can use input text with "list" attribute, which refers to the datalist of values.
您可以使用带有“list”属性的输入文本,该属性指的是值的数据列表。
<input type="text" name="city" list="cityname">
<datalist id="cityname">
<option value="Boston">
<option value="Cambridge">
</datalist>
This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist
这将创建一个自由文本输入字段,该字段还有一个用于选择预定义选项的下拉列表。例如归属和更多信息:https: //www.w3.org/wiki/HTML/Elements/datalist
