title: Sitecore: Set a relative data source while using branch
body: <p>I'm trying to use the branch template for the first time.</p>
  
  <p>Here I need to give an Item as data source for a treelist field for another item. And both are in the same branch.</p>

  <p>Before using the branch, In the data template of Menucollection, I given the path of 'MenuItems' directly. With branching how we can make this dynamic?, since each item I created using branch may have different items in 'MenuItems'. </p>
