Fieldsets
It is possible to group actions together in a "group", which is not a directory, but is called a "fieldset". This is an example of a fieldset that contains two folders.

Fieldsets are defined under a dashboards in your config.yaml.
config.yaml
dashboards:
- title: My First Dashboard
contents:
- title: Fieldset 1
type: fieldset
contents: []
- title: Fieldset 2
type: fieldset
contents: []
Fieldsets are also generated for you when you use entities.
config.yaml
dashboards:
- title: My First Dashboard
contents:
- title: Fieldset 1
type: fieldset
entity: server
contents:
- title: Start {{ server.Name }}
- title: Shutdown {{ server.Name }}
