I'd like to create a text field with a dropdown list that lets the user choose some predefined values. The user should also be able to type a new value or select a predefined one from a dropdown list. I know that I can use two widgets for that but in my app it would be more ergonomnic if it was unified in a one widget.
Is there a standard widget or do I have to use a third party javascript?
How about browser portability?
You can accomplish this by using the <datalist>
tag in HTML5.
<input type="text" name="product" list="productName"/>
<datalist id="productName">
<option value="Pen">Pen</option>
<option value="Pencil">Pencil</option>
<option value="Paper">Paper</option>
</datalist>
If you double click on the input text in the browser a list with the defined option will appear.
