JetFormBuilder (Core Plugin) GPL Overview:

Form building is not about guesswork. Build the backend structure and style every form component at once. A layout you create in the editor will be the end result you get on the front end.

• 18+ Form Field Blocks
• Multi-Column Layouts
• Custom HTML Addition
• Inline Fields Editing
• Free Styling Plugin

• Conditional Logic
  Create smart online forms that react to User choices and personalize the form experience.
• Conditional Fields
  Set any form field states to easily show, hide, enable, disable, or make them required/optional.
• Conditional Actions
  Set the conditions according to which the post-submit actions will be executed.
• Dynamic Values
  You can link the desired field to its relevant data from the database. In this way, some field values will be prefilled on the frontend.
• Calculated Content & Hidden Fields
  Build calculator forms that perform basic and complex calculations. Too many system fields in a form? Not a problem. JetFormBuilder lets you make them invisible to users.
