NodumForms offers 10 block types to collect different kinds of information.

Text inputs

Short Text — A single-line text field. Use for names, titles, URLs, or any brief text. Shows a smart placeholder based on the question (e.g. "John Smith" for name fields).

Long Text — A multi-line text area. Use for messages, descriptions, feedback, or any longer-form text input.

Choice blocks

Multiple Choice — Radio buttons for single selection, or checkboxes when "Allow multiple" is enabled. Add as many options as you need. Options can be reordered by dragging.

Dropdown — A select menu that saves space when you have many options. Respondents click to expand and pick one option.

Rating

Rating — A number scale (default 1–5, configurable up to 10). Respondents click a number to rate. Great for satisfaction scores, NPS, and quality assessments.

Binary

Yes / No — Two large buttons for a simple binary choice. Use for consent questions, confirmations, or any yes/no scenario.

Contact fields

Email — An email input with built-in format validation. Submissions are rejected if the email format is invalid.

Phone — A phone number input. Accepts any format — no strict validation, so international numbers work fine.

Special blocks

File Upload — Let respondents attach files. Supported formats: PDF, DOC, DOCX, PNG, JPG, JPEG, GIF, WEBP. Maximum file size: 5MB per file.

CAPTCHA — Adds reCAPTCHA verification to prevent spam submissions. Place it at the end of your form, before the submit button.
