title: How to group multiple views in a ConstraintLayout
body: <p>I have added 3 buttons in a ConstraintLayout. I have added a button to disable or enable these buttons.</p>
  
  <p>If I was using normal LinearLayout. I could have put all the buttons in a Linear Layout and enable or disable that particular layout. </p>
  
  <p>But I am using ConstraintLayout. So I need to disable or enable all of these buttons, I believe that there must be a way in ConstraintLayout to group different views.</p>
  
  <p>Kindly guide me how to group views in ConstriantLayout</p>
