Connect Elementor Pro's Loop Grid to Advanced Custom Fields (ACF) Pro Repeater and Relationship fields.

The Elementor Loop Grid has a Query tab. Choose "ACF Repeater" or "ACF Relationship" from the dropdown.
This plugin allows you to use ACF Repeater and ACF Relationship fields as data sources for Elementor’s Loop Grid widget.
Key Features:
1. Configure the Loop Grid
2. Displaying Data in Your Loop Template (ACF Repeater)
Note that the preview within the template will not display the sub-field data. This is expected behavior because no applicable preview data can be set in Elementor.
3. Displaying Data in Your Loop Template (ACF Relationship)
