Meta Box fields
Meta Box custom fields as a dynamic source, with dot paths for nested values.
Meta Box fields are a dynamic source alongside WordPress and ACF. When the Meta Box plugin is active, Meta Box appears in the Source dropdown of the dynamic values panel; without the plugin the entry stays hidden.
Inserting a field
Pick Meta Box as the source and type the field name. The canvas previews the resolved value against the chosen preview post, so you see real content while you build. Before, After, and Fallback text work as with any dynamic value.
Nested values
The underlying token is {metaboxfield=<field>}, and a second part reaches inside structured fields: {metaboxfield=<field>,<path>}. The path is dot notation, walking groups by subfield name and cloneable rows by index:
{metaboxfield=contact,email}reads theemailsubfield of acontactgroup.{metaboxfield=team,0.name}readsnamefrom the first row of ateamfield.
Each segment steps one level deeper, to any depth.
What renders
Fields resolve through Meta Box itself, so values come back the way Meta Box returns them for the current post. The value that finally prints has to be a plain one, text or a number. For a structured field, point the path at the piece you want rather than at the structure.
