Blocks

A visual editor for long-form text and modular pages

The Blocks field is the perfect solution for complex single-column layouts and long-form text.

Blueprint setup

You can add the Blocks field to any fields section in your Panel like this:

fields:
  text:
    type: blocks

Field properties

Property Type Default Description
autofocus bool - Sets the focus on this field when the form loads. Only the first field with this property gets focus.
default array - Default value for the field, which will be used when a page/file/user is created
disabled bool - If true, the field is no longer editable and will not be saved
empty string - Customize the default text when the blocks field is empty
fieldsets array - Defines the allowed block types in the blocks field. See below.
help - Optional help text below the field
label - The field label can be set as string or associative array with translations
max int - Maximum number of allowed blocks
min int - Minimum number of required blocks
pretty bool false Saves pretty printed JSON in text files
required bool false If true, the field has to be filled in correctly to be saved.
translate bool true If false, the field will be disabled in non-default languages and cannot be translated. This is only relevant in multi-language setups.
when - Conditions when the field will be shown (since 3.5.1)
width string 1/1 The width of the field in the field grid. Available widths: 1/1, 1/2, 1/3, 1/4, 2/3, 3/4

Defining Fieldsets

By default, the block selector shows a single list of available block types in alphabetical order.

fields:
  text:
    type: blocks

However, you can fully customize the selector for new block types with sorted block types and groups.

To change the order of available blocks, list them manually with the fieldsets option:

fields:
  text:
    type: blocks
    fieldsets:
      - heading
      - text
      - list
      - image
      - gallery
      - video
      - code
      - markdown

Groups

You can group block types in the block selector for a better overview of the available options. This is particularly useful when your blocks lists gets longer once your start creating your own custom blocks.

To create such groups, use the Blocks field's generic "group" block type:

fields:
  text:
    type: blocks
    fieldsets:
      text:
        label: Text
        type: group
        fieldsets:
          - heading
          - text
          - list
      media:
        label: Media
        type: group
        fieldsets:
          - image
          - video
      code:
        label: Code
        type: group
        fieldsets:
          - code
          - markdown

Closed groups

By default, all groups are open. With very long list, you might want to close groups of blocks that are used less frequently with the open: false option:

fields:
  text:
    type: blocks
    fieldsets:
      text:
        label: Text
        type: group
        fieldsets:
          - heading
          - text
          - list
      media:
        label: Media
        type: group
        fieldsets:
          - image
          - video
      code:
        label: Code
        type: group
        open: false
        fieldsets:
          - code
          - markdown

Default values

You can set default blocks/values for blocks fields which will prepopulate the field using the default prop. The type property is required, but default blocks can be empty or filled with example content.

Empty default block

fields:
  text:
    type: blocks
    default:
      - type: text

Default block with content

fields:
  text:
    type: blocks
    default:
      - type: text
        content:
          text: Write something great…

Multiple block types

You can also set multiple default block entries:

fields:
  text:
    type: blocks
    default:
      - type: heading
        content:
          level: h2
          text: A heading
      - type: text
        content:
          text: Write something great…

Block types

Custom block types

Kirby's built-in blocktypes are not enough? Create your own! Check out our extensive documentation on custom block types, from basic to advanced:

Extending core blocks

From modifying the output to how they are previewed in the Panel, you can also overwrite Kirby's built-in block types:

Blocks in your templates

If you don't want to care about the HTML for each individual block, you can echo the entire blocks collection to render all blocks.

<?= $page->myBlocksField()->toBlocks() ?>

Looping through blocks

Looping through blocks to control their HTML can be very powerful. You can assign custom CSS classes, IDs for links and more.

You don't need to render the HTML for each individual block in the loop though. You can wrap the block with your custom HTML and then echo the $block object to render the matching block snippet.

<?php foreach ($page->myBlocksField()->toBlocks() as $block): ?>
<div id="<?= $block->id() ?>" class="block block-type-<?= $block->type() ?>">
  <?= $block ?>
</div>
<?php endforeach ?>

Manually loading snippets

Sometimes you might wish to customize the way block snippets are loaded. Maybe you want to inject more snippet variables.

<?php foreach ($page->myBlocksField()->toBlocks() as $block): ?>
<div id="<?= $block->id() ?>" class="block block-type-<?= $block->type() ?>">
  <?php snippet('blocks/' . $block->type(), [
    'block' => $block,
    'theme' => 'dark'
  ]) ?>
</div>
<?php endforeach ?>

… or load snippets from a different location …

<?php foreach ($page->myBlocksField()->toBlocks() as $block): ?>
<div id="<?= $block->id() ?>" class="block block-type-<?= $block->type() ?>">
  <?php snippet('blocks/custom/' . $block->type(), [
    'block' => $block,
    'theme' => 'dark'
  ]) ?>
</div>
<?php endforeach ?>

Configuration

You can configure the default setup of your Blocks field in your config.php

/site/config/config.php
<?php

return [
  'blocks' => [
    'fieldsets' => [
      'text' => [
        'label' => 'Text',
        'type' => 'group',
        'fieldsets' => [
          'text',
          'heading'
        ]
      ],
      'media' => [
        'label' => 'Media',
        'type' => 'group',
        'fieldsets' => [
          'image',
          'video'
        ]
      ]
    ]
  ]
];

Builder & editor migration

Builder and editor field migration has been removed since Kirby 3.7. If you are upgrading to Kirby 3.7+ from an older version with the builder or editor field, please first upgrade to Kirby 3.6 and migrate your content to the new blocks format.
