title: Wix create subgroups in list repeater
body: <p>I want to create subgroups in a list repeater on a dynamic page on Wix. In other words I want to group items from a database based on a category. I would like to achieve a structure like this on one dynamic page (example countries):</p>
  <pre><code>Group Title 1 (e.g. Europe)
  
      Repeater cell 1 (eg. Denmark)
  
      Repeater cell 2 (e.g. Italy)
  
      Repeater cell 3 (e.g. Greece)
  
  
  Group Title 2 (e.g. South America)
  
      Repeater cell 1 (eg. Brasil)
  
      Repeater cell 2 (e.g. Chile)
  
      Repeater cell 3 (e.g. Peru)
  </code></pre>
  <p>and so on.</p>
  <p>So the structure of the cells is the same, I just want to add some kind of grouping of the elements based on a category.</p>
  <p>How can I achieve this? Has anybody any suggestions?</p>
  <p>Thank you in advance!</p>
