Question themes can be used to customize existing question types and
change their visual appearance. Question themes can only be built on
core Question types.
To access the question themes, go to Configuration -> Advanced -> Themes -> Question themes.
Here you can see question types, core question themes, and user question themes.
Question Themes are by default visible, but can be switched off. Once turned off, they will no longer be displayed inside the question type selector.
