title: How to make a single field contain multiple pieces of data that are individually sortable?
body: <p>I am trying to make a column than contains project types.The projects could be any combination of nine different categories.</p>
  
  <p>For example, I have some projects that would be categorized as Education, some that would be Health, some that would be Food Security, etc.</p>
  
  <p>But I have some projects that are both Health and Food Security. In the drop-down sort I would like to be able to check Health and sort everything that contains Health, even if it also has other project types. I do not want to have to check and individual category called "Health and Food Security" in order to get the project to come up.</p>
