H5P offers two main ways for Drupal site builders and developers to customize how H5P behaves.
H5P defines several hooks allowing Drupal users to customize the design and behaviour of H5Ps.
The H5P specific Drupal hooks are documented in h5p.api.php
In addition H5P stores scores and have made a Views integration for its' score data.
Our views integration allow Drupal site builders to customize how score data are displayed. Should they be filtered on a course or a school? Maybe it should be possible to search for users by their name? The views 3 integration makes sure that the results data may be combined with all the existing data in the Drupal installation and displayed and behave in many different ways.
