What is HTML Form Builder?

A form builder generates the repetitive HTML needed for web forms: labels, inputs, textareas, selects, radio groups, checkboxes, required attributes, form action, method, and optional CSS. It helps developers and content teams create clean starter markup without manually typing every field.

This builder focuses on practical HTML output rather than hosted form storage. You control the action URL and method, then copy or download markup that can be connected to your own backend, static site form provider, or application framework.

How to Use HTML Form Builder

1

Set the form action, method, ID, class, submit text, and layout.

2

Add fields from the field menu or quick-add buttons.

3

Select a field to edit its type, label, name, placeholder, options, and required state.

4

Preview the form to check the layout.

5

Copy the generated HTML or download it as a file.

Common Use Cases

  • Create contact form markup for a static website.
  • Prototype signup and onboarding forms before implementing backend validation.
  • Generate select, radio, and checkbox groups without repetitive typing.
  • Build form examples for documentation, tutorials, or component specs.
  • Create accessible starter markup with connected labels and inputs.

Example Input and Output

A contact form with name, email, plan, and message fields generates labeled HTML with optional CSS.

Builder settings
Fields: Full name, Email address, Plan select, Message textarea
Generated HTML
<form id="contact-form" class="wtp-form" action="/contact" method="post">...</form>

Validation

The builder can mark fields as required, but production forms should still validate submissions on the server.

Privacy

Form configuration and generated HTML stay in your browser. No field labels or markup are uploaded.

Frequently Asked Questions

Does this store form submissions?
No. The tool generates HTML markup only. Connect the form action to your own backend, serverless function, or form handling service.
Can I add select or radio options?
Yes. Select and radio fields include an options editor where each line becomes one option.
Does the generated form include CSS?
It can. Keep "Include CSS styles" enabled for a starter style block, or turn it off if your site already has form styles.
Are labels connected to inputs?
Yes. Generated labels use the field ID in their for attribute, and inputs use the same ID.
Is anything uploaded?
No. The builder runs in your browser and only generates markup locally.
