You can simply add a FontAwesome icon to your select dropdown as text. You only need a few things in CSS only, the FontAwesome CSS and the unicode. For example 
:
select {
font-family: 'FontAwesome', 'Second Font name'
}
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>
<select>
<option>Hi, </option>
<option>Hi, </option>
<option>Hi, </option>
<option>Hi, </option>
<option>Hi, </option>
</select>
The Unicode can be found when you click on an icon: Fontawesome
According to the comment below and issue on Github, the Unicode in select elements won’t work on OSX (yet).
Update: from the Github issue, adding multiple
attribute to select
element makes it work on:
OSX El Capitan 10.11.4
- Chrome version 50.0.2661.75 (64-bit)
- Safari version 9.1
- Firefox version 45.0.2
select{
font-family: FontAwesome, sans-serif;
}
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>
<select multiple>
<option> 500px</option>
<option> Adjust</option>
<option> Adn</option>
<option> Align-center</option>
<option> Align-justify</option>
<option> Align-left</option>

</select>
