title: Adding Radio Button to Advanced Custom Field
body: <p>I'm pretty new to ACF. I am editing this page: <a href="http://pear.staging.wpengine.com/schizophrenia-semi-final/" rel="nofollow">http://pear.staging.wpengine.com/schizophrenia-semi-final/</a> which has an ACF for the intro image and another for the intro text. In the template, this is the code:</p>
  
  <pre><code>&lt;?php $bg1 = (get_field('pear_intro_image')) ? get_field('pear_intro_image') : ''; ?&gt;
  &lt;section id="intro" class="section" style="background-image: url('&lt;?=$bg1[sizes][large]?&gt;');"&gt;
    &lt;div class="container "&gt;
      &lt;div class="row"&gt;
        &lt;div class="col-sm-8 col-sm-offset-2 text-center"&gt;
          &lt;?= get_field('pear_intro_text') ?&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  </code></pre>
  
  <p>The style "background-image" sets the position of the image to 'center center'. The client wants to remove that class and instead add a radio button to the ACF with the option for aligning it to the top, center or bottom.</p>
  
  <p>I am not sure how I would go about this. Can anyone point me in the right direction?</p>
