Exploring Methods to Conceal Cells in Livebook for Elixir Learning Exercises

The post by WoT_Abridged discusses the desire to create a learning environment within Livebook for Elixir students that includes problems, user answer input, and a scratchpad for code testing. The author wants to preserve the cleanliness of the page and avoid giving away too much information by hiding the testing cell that uses ExUnit to provide feedback. Although the page could become cluttered and the testing cell could inadvertently provide hints on how to solve the problem, the intention is to only show users a pass or fail status. The author is considering options such as utilizing the Kino Livebook library, linking two livebooks together, or using Livebook Smartcells but has not found a clear solution and is seeking advice from others who might have tackled this issue.
