ACF Blocks
Custom Advanced Custom Fields (ACF) blocks. Each block has its own reference file in references/ with field keys, types, examples, and markup.
How to Use
- Read the specific block reference file before generating markup
- Use the exact field keys shown (prefix varies: most use
field_, CTA usesacf_) - Blocks using InnerBlocks wrap standard WordPress blocks (paragraphs, lists) inside them
- Self-closing blocks (
/-->) contain all data in the JSON attributes - All string values in data must be strings (even numbers:
"4.5"not4.5) - Repeater rows use sequential keys:
row-0,row-1,row-2

<!-- wp:acf/block-name {"name":"acf/block-name","data":{...}} /-->
InnerBlocks block (callout, opinion-box, cta)
<!-- wp:acf/block-name {"name":"acf/block-name","data":{...},"mode":"preview"} -->
<!-- wp:paragraph -->
<p>Content goes here as standard WordPress blocks.</p>
<!-- /wp:paragraph -->
<!-- /wp:acf/block-name -->
