title: How to access the data in the view list and make the display conditions with laravel-backpack
body: <p>I would like to hide buttons in laravel-backpack (in list view) only if a certain condition is true.</p>
  
  <p>This condition, I would like to do with a data one of my items.</p>
  
  <p>For example, if the status of the article is "Published", remove the edit button.</p>
  
  <p>But I can not access this data in my ItemCrudController.</p>
  
  <p>What I would like to do:</p>
  
  <pre><code>public function setup()
  {
    if(myData == 'published'){
      $this-&gt;crud-&gt;removeAllButtons();
    }
  }
  </code></pre>
  
  <p>Do you have an idea of how? Thank you very much!</p>
