From v2.9.0 this widget is deprecated. We recommend to use the new version in the future sites, but we will not remove the old version.
The ACF Relationship widget lets you display related Post objects (single or multiple) defined in an ACF Relationship field of the current post.
Invert direction
ACF Relationship doesn't support natively bidirectional relationships, but our widget can simulate and resolve it. It retrieves all posts that are associated with the current post.
For example: if you have associated the Authors to the Books with an ACF Field stored in Books CPT, normally you can only list the Authors in Books single page.
With this Inverted direction setting, you will be able to list all Books associated with Authors on the Authors single page.
Render Mode
With a custom presentation layout:
Title list, optionally linked
Text editor, to create your own structure. It supports HTML and Tokens;
Elementor Template.
For a more complete solution, you can use dynamic data of related post to build a complex structure rendered as:
Natural, for the element in the same wrapper;
List, unordered, and ordered;
Grid, display in columns as a grid;
Accordion, as collapsible accordion panels;
Select, a form select that let the user select one of the related posts;
Tabs horizontal and vertical.
