[SOLVED] Check List/Task List

Hello,

I didn't find in in the manual how can be used Check List and TAsk List ? Why can't we put a name on it ?

My need is to be able to creat a model list of tasks (that, I managed doing it) and then being able to add a task which will use this.
For example :
Chek list "training"
Room
Invitation sent
Meal
...

And when I create a task Training, I can use this check list.

But I don't see how

Yes I saw that. But how use it once it is defined ?

Ok thanks ! Not really easy to use but I can manage something
