title: QlikView : get data filtered in pivot table
body: <p>I found a great tutorial for <a href="http://www.qlikfix.com/2014/07/08/building-nicer-dynamic-multibox/" rel="nofollow noreferrer">building a nicer (dynamic) multibox, without extensions</a>.</p>
  
  <p>I was able to use it, and I really love it.
  However, I have an issue: 
  if I use a multibox with a master detail table, then if I filter it from detail then master will automatically selected. The below example shows a normal multibox at the top, and dynamic/pivot multibox at the bottom:</p>
  
  <p><img src="https://i.stack.imgur.com/jezWk.jpg" alt="enter image description here"></p>
  
  <p>How I can achieve this with my dynamic multibox?</p>
  
  <p>For the label, I use:</p>
  
  <pre><code>=if(IsNull(GetFieldSelections(master)) = -1, 'Master',GetFieldSelections(master))
  </code></pre>
  
  <p>with this, I can set 'Master' as the label.</p>
  
  <p>I can see data has seen filtered but I didn't find a function to get data that has been filtered to set it in the label, maybe someone here can give me an advice to solve this.</p>
