title: Activeadmin stops my jQuery working
body: <p>I'm using jquery drag and drop in my app and it works fine.</p>
  
  <p>I then added activeadmin and it stops my jquery working.</p>
  
  <p>I get this error</p>
  
  <pre><code>$(".draggable_article_image").draggable is not a function
  </code></pre>
  
  <p>If I remove this line from active_admin.js</p>
  
  <pre><code>//= require active_admin/base
  </code></pre>
  
  <p>it starts working again.</p>
  
  <p>Any ideas?</p>
