My English is not good, but I am going to try to explain the "template" functionality.
The template is useful when you want a different layout, not rows like moodle is by default.
The template is the HTML in the topic summary and you can insert the resources into the HTML with your name between double brackets, por example:
Next an example:
This example template use a three columns layout. Resources are inserted
in the diferents columns and the completion "check" looks with the
resource (this is not posible with the "activities auto link" filter).
You can chose if the icon looks with
the activity name: option Show icon in resource links in summary.
In edition mode, the course looks like the next image.
I hope my explanation clarifies things a bit.
Ah, perfect. Thank you so much David! That helps tremendously, and I now have a working example to experiment with.
Your explanation is very appreciated!
