helm to iterate a list of lists - yaml

Question

Given the follow values.yaml
configurations:
endpoints:
- firstEndpoint
- firstPath
- secondPath
- secondEndpoint
- thirdPath
- fourthPath
I need to generate different resources from those values in the following way:
- name: firstEndpoint
paths:
- firstPath
- secondPath
- name: secondEndpoint
paths:
- thirdPath
- fourthPath
I can do this if "endpoints" were to be a map, instead of a list/array, but in this case, I need "endpoints" to be a list of endpoints, and "paths" to be a list of paths for each endpoint.
How could this be achieved?

As David Maze said. Your proposed endpoints: isn't valid.
You may try this:
values.yaml
configurations:
endpoints:
- firstEndpoint:
- firstPath
- secondPath
- secondEndpoint:
- thirdPath
- fourthPath
(Note the : after firstEndpoint and secondEndpoint)
template/cm.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: test
data:
test: |-
{{- range $_, $item := .Values.configurations.endpoints }}
{{- range $k, $v := . }}
- name: {{ $k }}
path:
{{- range $_, $path := $v }}
- {{ $path }}
{{- end }}
{{- end }}
{{- end }}
output
apiVersion: v1
kind: ConfigMap
metadata:
name: test
data:
test: |-
- name: firstEndpoint
path:
- firstPath
- secondPath
- name: secondEndpoint
path:
- thirdPath
- fourthPath
