Both Joomla and WordPress plugins are not any more available to buy and download.
The adaptative version is introduced in Extended version 1.4.11
It allows to display activities height relative to their duration and to display a time scale on the left of the timetable.
The grid and the management system is the same as the fixed timetable type, there is two important differences between the adaptative and the fixed version:
1/ It is needed to create a "blank" activity to insert it before "real" activities, if you want to create an offset before these activities, like in the example below, because empty blocks are not displayed in the front.
2/ the "height" is replaced in the adaptative view by a "height factor" that multiply the duration of the activity. For example a 60' activity with a 1.5 height factor will have a height of 90px.
