Prevent iPhone from zooming in on `select` in web-app
I've got this code:
<select>
<option value="c">Klassen</option>
<option value="t">Docenten</option>
<option value="r">Lokalen</option>
<option value="s">Leerlingen</option>
</select>
Running in a full-screen web-app on iPhone.
When selecting something from this list, the iPhone zooms in on the select-element. And doesn't zoom back out after selecting something.
How can I prevent this? Or zoom back out?
Answer
It is probably because the browser is trying to zoom the area since the font size is less than the threshold, this generally happens in iphone.
Giving a metatag attribute "user-scalable=no" will restrict the user from zooming elsewhere. Since the problem is with select element only, try using the following in your css, this hack is originally used for jquery mobile.
HTML :
<meta name="viewport" content="width=device-width, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
CSS:
select{
font-size: 50px;
}
