[SOLVED] Front matter array with multiple values

Help

Could be a YAML thing. To do an array try:

z: [c, d, e]

You can specify arrays or lists on a single line.

items: [ 1, 2, 3, 4, 5 ]
names: [ "one", "two", "three", "four" ]

Or, you can put them on multiple lines.

items:
  - 1 
  - 2 
  - 3
  - 4 
  - 5 
names:
  - "one"
  - "two"
  - "three"
  - "four"

The multiple line format is useful for lists that contain complex objects instead of scalars.

items:
  - things:
      thing1: huey
      things2: dewey
      thing3: louie
  - other things:
      key: value

An array can contain any valid YAML value. The values in a list do not have to be the same type.
