title: Tableau Legend Highlighting
body: <p>I have created Tableau worksheet and color coded my chart by Department name and added legend to my workbook. Usually Tableau allows legend highlighting - you can select an item in the legend and all related items in workbook are highlighted. For some reason "Highlight Selected Items" option is disabled for the legend in my workbook.</p>
  
  <p>Any idea why this is happening?</p>
  
  <p>Thanks</p>
