WP Grid Builder Meta Box Addon GPL Overview:
This add-on adds support for the Meta Box plugin. WP Grid Builder natively works with WordPress custom fields. However, if you use a dedicated custom fields plugin like Meta Box, the values may be stored in such a way that they require additional processing to properly filter the content.
This add-on supports all field types generated by the Meta Box plugin and makes it easy to filter content, regardless of field complexity. For example, you can filter by a cloneable multiple-select field placed in a group.
Easily filter by any type of field from Meta Box
Display field values in cards from custom field block
Once the add-on is activated, you will be able to search for Meta Box fields from the facet settings and card builder (custom field block). You just need to search for “meta box” and you will see as results all available fields from the Meta Box plugin.
