title: How to expand/collapse groups in SSRS
body: <p>I have a very simple report with only 4 fields. The first field is the Customer group, the parent (and only) group. </p>
  
  <p>The trouble is, a lot of the Customers have many entries, so it's not easy to thumb through the report --there are a lot of pages.</p>
  
  <p>The field headers are arranged in the following order: </p>
  
  <p><strong>Customer | CreatedDate | Object | Value</strong> </p>
  
  <p>I wanted to make the Customer field/group collapsible/expandable. I would like the initial setting to have all Customer group rows collapsed at the start so the user can expand the Customer they choose.</p>
  
  <p>I've tried about 4 different tutorials I found on Google and nothing's working.</p>
