Alright, let me try to explain what I'm trying to do.

I have a collection called "staff", which contains approx. 30 people. This collection is shown on a page ("/our-staff") and every staff member has their own profile page.

I need to show which of these staff members are working today.

I've added a toggle field in the fieldset, so I could just have my client edit all collection items and either swipe the toggle on or off. My code on the "our staff"-page contains the following:

// partial.html

{{ collection:staff }}
...
{{ if working_today }}
<span>Working today</span>
{{ /if }}
...
{{ /collection:staff }}

That works, but it is a hassle to (potentially) have to edit 30 entries every day.

I'm puzzling with putting this information in a separate global:

// global_fieldset.yaml

fields:
  my_collection_field:
    type: collection
    collection: staff

But now I have to somehow link this global to the items in the collection. So... if Person X is working today and I add him to the global, I would like to have the {{ collection }} on the page template read that and output something on that template.

Hope that this makes sense :-D
