Please add custom checkout fields

Cemil Jim Alyanak We built custom checkout fields in CartCubes Toolbox. You can add field groups with a heading, drag them to reorder, and place them after name/email, after billing, or before payment. Field types are text, textarea, checkbox, select, date, and file upload. You can show a group only for selected products, categories, brands, WordPress roles, or FluentCRM lists and tags. Answers save on the order and show in the admin order view and the customer account.
