Or via npm:

<link rel="stylesheet" href="./bower_components/mdl-selectfield/dist/mdl-selectfield.min.css">
...
<script src="./bower_components/mdl-selectfield/dist/mdl-selectfield.min.js"></script>

Basic use

To use any MDL component, you must include the minified CSS and JavaScript files using standard relative-path references in the <head> section of the page, as described in the MDL Introduction.

To include a MDL select field component:

1. Code a <div> element to hold the text field.

<div>
...
</div>

2. Inside the div, code an <select> element, add the options and add an id attribute of your choice.

<div>
  <select id="gender">
    <option value=""></option>
    <option value="male">Male</option>
    <option value="female">Female</option>
  </select>
</div>

3. Also inside the div, after the select field, code a <label> element with a for attribute whose value matches the select element's id value, and a short string to be used as the field's placeholder text.

<div>
  <select id="gender">
    <option value=""></option>
    <option value="option1">option 1</option>
    <option value="option2">option 2</option>
  </select>
  <label for="gender">User gender</label>
</div>

4. Add one or more MDL classes, separated by spaces, to the div container, select field, select label, and error message using the class attribute.

<div class="mdl-selectfield mdl-js-selectfield">
  <select id="gender" class="mdl-selectfield__select">
    <option value=""></option>
    <option value="option1">option 1</option>
    <option value="option2">option 2</option>
  </select>
  <label class="mdl-selectfield__label" for="gender">User gender</label>
  <span class="mdl-selectfield__error">Select a value</span>
</div>

The select field component is ready for use.
