title: How to hide option in drop down menu?
body: <p>I'm trying to hide the &quot;Select Value&quot; option in the drop down menu of a plugin I have for my wordpress, I've tried the following code:</p>
  <pre><code>div.calc-drop-down-box.calc_dropDown_field_id_0 {
      
              visibility: hidden !important;
  
  }
  </code></pre>
  <p>But this doesn't work. What am I doing wrong?</p>
