title: Is it possible to set Select element width in percentage?
body: <p>I have a select element in an HTML page, I'd like to set its width to 100% (via CSS) but it doesn't work and the width only changes according to the width of the longest option.
  Only when I set a width in pixels, it works.</p>
  
  <p>Is it possible to set the width in percentage? or is there a workaround?</p>
