Editing / Options

Input Options

Hidden Fields

Control which front matter fields your editors see with the hidden option.

_options:
  layout:
    hidden: true

Hidden fields can be edited with modal-style Editor Links.

Alternatively, hide front matter fields by prefixing the key with an underscore (e.g. _hidden_text).

Code Blocks

Change the appearance and behaviour of your front matter code blocks to fit your use case and brand.

_options:
  code_block:
    tab_size: 2
    show_gutter: false
  javascript_code_block:
    tab_size: 4
    theme: dawn

Option	Values
tab_size	Integer (optional, defaults to 4)
theme	String, one from themes (optional, defaults to monokai)
show_gutter	true or false (optional, defaults to true)

tab_size controls how many spaces lines are auto indented.

theme controls the appearance of the editor.

show_gutter toggles line numbers and code folding controls.

Array Structures

Provides initial values for newly created items in arrays. Configured globally in _config.yml or per file in front matter with a _defaults object.

For example, set the structure for new items in a gallery array with:

_array_structures:
  gallery:
    label: Image
    icon: image
    value:
      image: /placeholder.png
      caption:

Define multiple structures if you need editors to add different types to an array:

_array_structures:
  gallery:
    - label: Image
      icon: image
      value:
        image: /placeholder.png
        caption:
    - label: External link
      icon: link
      value:
        url:
        title:

Alternatively, configure on a custom scope with Jekyll defaults:

defaults:
  - scope:
      path: ''
      type: ''
    values:
      _array_structures:
        gallery:
          - label: Image
            icon: image
            value:
              image: /placeholder.png
              caption:
          - label: External link
            icon: link
            value:
              url:
              title:

The label is used in the array interface to display what kind of item(s) editors can add.

The icon is a Material Design icon name for customising how the array item preview.

New array items have their keys and values populated from the value you set. If no structure is defined, new array items clone the structure from existing array items.

Array structures also apply when editing CSV, YAML and JSON files.
