thanks in advance.
Just edit the course summary.
there is no option to minimize the summary. moodle mobile supports "show more" in course summary. but in moodle web i did'nt find it. can someone tell me step by step.
Ah, that would need code changes with an option that uses 'core_text::strlen()' (PHP solution or could be a JS solution) therefore if on the MoodleCloud then out of your control. Would therefore need core to be enhanced via Moodle Tracker. Thus at the earliest would possibly be M3.4 if not M3.5 next May.
