Hello Hervé and thank you for posting.
First of all, MyShortlist is not intented to automatically include any button in your site. You have to configure where to show it.
Without Custom Blocks, it will not show the add button in a category page, or agenda page, but only in a single article page or single event page. So, to show the MyShortlist Button in the Agenda page, you need to use Custom Blocks, which is a relatively new feature, on which we are working to produce a nice tutorial.
Secondly, to have different MyShortlist lists without allowing the user to create them, you have to have different module instances. One for each list you want. One of the first options in MyShortlist is the "Default List ID (Cookie Prefix)". There it mentions: "Use this prefix, if you would like to have more than one My ShortList lists on your site."
So, to create multiple lists, you need to create multiple MyShortlist modules. Write a different module title. For example: "My Wishlist" and "My Favorites".
In "My Wishlist" module, write "My Wishlist" as the Default List Name.
Write "wishlist" as the Default List ID.
Set Allow Multiple Lists to No.
In "My Favorites" module, write "My Favorites" as the Default List Name.
Write "favorites" as the Default List ID.
Set Allow Multiple Lists to No.
That will produce two different modules that have two different lists.
Let's assume you want another module, that is only for some user group, that allows them to edit lists.
Create the other module "My Lists".
Write the default list you want (name and cookie prefix) and set Allow Multiple Lists to Yes.
Then, on the usual module options on the right, select for which users it will be visible.
This way, they will be able to edit their lists.
I checked your page and the Add button doesn't work because of an issue with the base href.
Please mail me at me@mavxr.com so that we can debug that.
Thanks again.
