AcroForm List Box HTML Twin

AcroForm list boxes, including one that permits several selections at once. This HTML twin carries the same canonical field names as the AcroForm PDF of the same name, so a filler can be tested against both representations of one form.

What is a .html file?

HTML (HyperText Markup Language) is the structural markup language of the web, using nested tags to define document content, semantics, and links. It is typically paired with CSS for presentation and JavaScript for behavior. It is the foundational format rendered by browsers.

How to use this file

Use an example HTML file to test parsers, DOM construction, sanitization of untrusted markup, and rendering or scraping pipelines.

How to use this file for testing

“AcroForm List Box HTML Twin” is a deterministic Novus Examples fixture for Form testing, Form parsing, Autofill testing, HTML parsing. HTML and PDF form files for testing scrapers, autofill, validators, and PDF form fillers across real-life use cases.

Documented properties for this file: 4 fields. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

This form is fictional SAMPLE content for tooling tests (autofill, scrapers, PDF fillers). It is not an official government, bank, or clinic form. Open the HTML offline or fill the PDF in any viewer; the demo submit path never stores data.

Embed this form

It's a single self-contained HTML file (inlined CSS, native validation, no external requests). Download it, host it on your own site, and drop it into any page with an iframe.
