It is not a form plugin: activate it and it works with Contact Form 7, Fluent Forms, Snow Monkey Forms, WPForms, Forminator, MW WP Form and plain HTML forms. No shortcode and no per-form setup are needed. #### Features * **Furigana auto-fill** – type a name (with a Japanese IME) and the reading is filled into the furigana field, in hiragana or katakana. Deleting the name removes the matching furigana. * **Full-width to half-width conversion** – full-width digits and symbols in phone number, postal code, email and URL fields are converted when the field loses focus. * **Move to the next field on Enter** – pressing Enter no longer submits the form by mistake. The Enter that confirms IME conversion is ignored. Search boxes and other single-field forms are left alone. * **“Required” badges** – a small red “Required” badge is added to the label of each required field. Asterisks added by the form plugin are hidden for those fields. * **Valid / invalid colours** – invalid fields get a red border and light red background, valid fields a green border and light green background. Empty optional fields count as valid. * **Validation messages in Japanese** – for the kana type, phone number, postal code, email and URL format. * **No pinch-zoom on smartphones** – inputs smaller than 16px are raised to 16px, larger ones are kept. * **Every feature can be switched off** in the Suisui Form menu. #### Works with * Contact Form 7 * Fluent Forms * Snow Monkey Forms * WPForms (Lite) * Forminator * MW WP Form * Forms pasted as HTML from external services (for example MyASP) Forms embedded in an `iframe` (for example Google Forms) cannot be reached by any plugin on the host page, so they are not supported. #### When automatic detection is not enough Suisui Form works out which field is which from labels, placeholders and field names. If a field has an unusual name, add one of these CSS classes to the input (or to an element that wraps it): `fkwp-name`, `fkwp-kana`, `fkwp-hira`, `fkwp-kata`, ` fkwp-tel`, `fkwp-zip`, `fkwp-mail`, `fkwp-url`, `fkwp-required`, `fkwp-optional`,` fkwp-off`. The Manual settings tab explains each class. #### Address auto-fill Filling in an address from a postal code is not included. The free plugin zipaddr- jp works well alongside Suisui Form. #### Privacy Suisui Form does not collect or store anything users type, does not set cookies and makes no external requests. ## Screenshots [⌊the Suisui Form menu: turn each feature on or off.⌉⌊the Suisui Form menu: turn each feature on or off.⌉[ the Suisui Form menu: turn each feature on or off.

Optional: open the Suisui Form menu to switch features on or off. ## FAQ ### Does it replace my form plugin? No. It only adds helpers on top of the forms you already have. ### The furigana is not filled in on my smartphone. On smartphones, choosing a predictive-text candidate directly gives no reading, so the result can be incomplete. Furigana auto-fill therefore runs on desktop only by default. You can turn it on for smartphones in the settings. ### A field was not recognised correctly. Add one of the `fkwp-` classes listed in the Manual settings tab to that field. ### Does it work with forms inside an iframe? No. A page cannot change what is inside an iframe from another site. ### Is there a Pro version? A separate paid add-on, Suisui Form Pro, adds analytics (drop-off per field, completion rate, input time and more). The free plugin contains no analytics and nothing in it is locked. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Suisui Form – EFO for Japanese Forms” is open source software.
