<h4> In this session, we talk about opting out actions so that only relevant actions are available for the user. We also show
  how to place Global actions in sub-menus to build a complete menu bar. Furthermore, we explain Class Constraints and how they can be used to make the user aware of the rules they should obey. We also show the concept of DefaultStringRepresentation
  of objects. </h4>

  <em>To make your experience smooth, we set the main tags mentioned in the video to the right bar menu of this mini-player. Choose an interesting subtitle on the list and immediately get to the exact theme navigation item place in the video. Now you can pick any topic to be instructed on without watching the whole video.</em>
