Show Unchecked CheckBox List

Hi there,

The simplest way to do this is with our paid Core Booster extension, which has this functionality available out of the box: https://gravitypdf.com/shop/core-booster-add-on/

Alternatively, you can make use of developer hooks included in the plugin to change the field mark-up: https://docs.gravitypdf.com/v6/developers/filters/gfpdf_pdf_field_content
