How to create a 100% width select with SelectBoxIt.js

Question

I have some trouble creating a 100% width select box with SelectBoxIt.js

Even when setting the CSS width to 100%, the select box will not fill 100% of the container element.

CSS:

.test1, .test2, .test2 .selectboxit, .test2 .selectboxit-options {
  width: 100%;
}

HTML:

<select name="test2" class="test2">
  <option value="SelectBoxIt is:">SelectBoxIt is:</option>
  <option value="a jQuery Plugin">a jQuery Plugin</option>
  <option value="a Select Box Replacement">a Select Box Replacement</option>
  <option value="a Stateful UI Widget">a Stateful UI Widget</option>
</select>

Answer 1

js

$(".mySelect").selectBoxIt({ autoWidth: false });

and then css

.selectboxit-container {
    width: 100%;
}

    .selectboxit-container .selectboxit {
    width: 100%;
}
