HTML Forms
Six independent AcroForm checkboxes covering both tick states and four button styles. 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 rep
HTML Forms
Two AcroForm choice fields, one plain drop-down and one editable combo box. 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 representatio
HTML Forms
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 representatio
HTML Forms
One AcroForm radio field whose four kids share a parent, plus a second three-kid group. 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 r
HTML Forms
A signature block drawn as a ruled area with named text fields - not a digital signature field. This HTML twin carries the same canonical field names as the AcroForm PDF of the same name, so a filler can be tested agains
HTML Forms
Text fields carrying the comb, multiline, password and read-only AcroForm flags. 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 represen
HTML Forms
The screen an address verifier shows after standardising an entry: the original and the suggestion side by side as a radio choice, plus editable fields prefilled with the standardised form.
HTML Forms
A downloadable appointment-scheduling form: service selection, a date and time picker, and contact details.
HTML Forms
A booking form that separates the date from the slot, so a scheduler has to read a bounded date control and a radio list of times rather than a single free-text field. Includes an accessibility need and a reminder channe
HTML Forms
The billing-prefixed twin of the shipping address form, deliberately using the same visible wording so an autofill engine has to distinguish the two sections by their token prefix rather than by label text.
HTML Forms
The contact channel tokens - the five telephone parts, email, impp, url and photo - plus the one-time-code token that lets a browser or password manager offer a verification code. Includes the webauthn hint on the code c
HTML Forms
The identity half of the autofill vocabulary: honorific prefix and suffix, given, additional and family name, nickname, organisation, job title, birthday parts, sex and language. Each token appears once, on the control t
HTML Forms
The payment autofill tokens - cc-name, cc-given-name, cc-family-name, cc-number, cc-exp and its parts, cc-csc and cc-type - on a form that has no action, no script and no prefilled values. It exists to exercise token rec
HTML Forms
A single page whose visible questions depend on the request type chosen. Three mutually exclusive blocks are present in the markup at all times, so the same file exercises both an automation that reads the DOM and one th
HTML Forms
A downloadable mock-checkout form, shipping address plus a payment section that accepts the standard test card 4111 1111 1111 1111. Nothing is charged or stored.
HTML Forms
Every way HTML expresses a choice: a single select with a prompt row, a multiple select, a select with option groups, a radio group, a checkbox group and a lone checkbox - including options whose submitted value differs
HTML Forms
Controls stacking required, pattern, length and range rules at the same time, including two deliberately awkward cases - a pattern narrower than its length bound, and a step that cannot reach the maximum - for testing wh
HTML Forms
A form where a script adds and removes the mandatory flag at runtime. The attribute is absent from the shipped markup on purpose, so a validator that reads the file statically and one that reads the live DOM give differe
