Repeat an array with normal section
A normal section in CraftMyPDF is designed to work with array-type data in JSON data.
To enable data-binding for a section, select a normal section and in the Data binding selection, check on Enabled and use an expression to bind the JSON array to the Data Source.
In a data-bound section, you can access the data row by using the following expression:
{{ row.[field] }}
