This add-on lets you render ACF field groups inside BuddyForms so users can create and edit content from the frontend—while keeping ACF-powered meta in sync.
Highlights 
– Works with ACF Free and PRO (ACF must be installed separately). 
– Map ACF field groups to BuddyForms forms for frontend create/edit. 
– Supports common ACF field types (text, textarea, select, checkbox, date, color, maps, etc.). 
– BuddyForms Moderation support for review/approval workflows. 
– BuddyPress integration: sync selected ACF fields with xProfile.
<blockquote>
Note: This plugin integrates with Advanced Custom Fields; it does not bundle any ACF code or assets.
