PDF Download Selector Block

A block that allows a user to select a pdf to download.

How it Works (Generally)

1. The block makes use of both a render callback and the Interactivity API for performant and flexible form downloads and rendering
2. The block stores PDF files as an array in its attributes unless an external data store is selected (see below)

With An External Data Store (CPT)

If using a CPT as an external data source, the CPT must include the following ACF fields;

1. pdf_file a File Field that returns an array
2. A True/False field with the name use_post_title_as_form_name

ACF Fields must be exposed to the REST API for access in the block editor! See useAllowedCPTs hook and the render callback file for specific implementation.
