Overview
Building forms that fit different site needs can involve more than adding a few text fields. SigmaForms Pro gives WordPress site owners a visual builder for arranging form fields, along with options to customize field types and layouts. Use it to create forms for contact requests, surveys, lead capture, or event registrations, then adjust their appearance to fit the site's design.
The plugin includes controls for colors, fonts, spacing, borders, and backgrounds, plus single-column, multi-column, and inline layouts. Conditional logic can show or hide fields based on user input, while CAPTCHA and honeypot techniques help address spam. Email notifications and automatic replies support communication with submitters, and submissions can be exported to CSV for handling and follow-up.
Features
- Visual form builder: Arrange form fields with a drag-and-drop interface to build forms without coding, including contact, survey, lead capture, and event registration forms.
- Custom field types: Choose from fields such as text, email, dropdowns, checkboxes, and file uploads to collect the information a form requires.
- Styling controls: Adjust form colors, fonts, spacing, borders, and backgrounds to coordinate its appearance with the rest of a website.
- Flexible form layouts: Set up forms in single-column, multi-column, or inline layouts to suit different content and page arrangements.
- Conditional field display: Use conditional logic to show or hide fields according to a user's input, shaping the fields presented in a form.
- Spam protection: Use CAPTCHA and honeypot techniques to help protect forms from spam and automated submissions.
- Notifications and exports: Send email notifications to your team and automatic replies to users, then export form submissions to CSV for follow-up.
Best for
- Businesses collecting contact requests and leads
- Bloggers creating surveys and reader forms
- Creators organizing event registrations

- Fixed Choosing a theme in Settings had no effect on existing forms, and forms on the global Custom theme kept their old colours
- Fixed REST submissions ignored the form's success message, unrated Ratings saved as 0, missed radios showed no error, and uninstall left license transients
