There are many customers/users who have given us a feedback that sometimes they would like to hide certain portion of the canvas (say the tile view) if possible and focus more on other visualisations on a canvas. OAC-Classic gives us the feature of creating collapsible sections on a dashboard page. A similar feature on DV would be great so that we can create a section on the canvas that can be expanded or collapsed as needed. This also has another potential benefit that we can create object level security on the section so that an entire section can be hidden for certain roles.
