title: Context Sublayout of Rendering Parameter
body: <p>I am using a rendering paramater template in a layout and need to work out the sublayout that the current parameters are attached to so that I can read a field from the sublayout in this context.</p>
  
  <p>I have found this example </p>
  
  <p><a href="https://stackoverflow.com/questions/18009470/set-queryable-source-on-rendering-parameter-template-field">Set queryable source on Rendering Parameter Template field</a></p>
  
  <p>but it only pulls back the context layout and not sublayout.</p>
  
  <p>Is there any way to do this?</p>
