## Overview

This is an embeddable JavaScript/PHP custom-tag form component. The main workflow is page markup with custom form and input tags → generated form UI → interactive input handling and validation → normal form submission to the host application. Major documented branches include address suggestions, phone prefixes, CAPTCHA, file uploads, and specialized color/date-time controls. Edges reflect the sampled imports and documented usage; unsampled request wiring and host-side PHP handling are left unspecified.

Main entry points: [`formComponent/createFormComponent.js`](https://github.com/francesca-22/javascript-form-component/blob/main/formComponent/createFormComponent.js) (Form builder), [`formComponent/js/checkForm.js`](https://github.com/francesca-22/javascript-form-component/blob/main/formComponent/js/checkForm.js) (Form validation), [`formComponent/components/modules/fade.js`](https://github.com/francesca-22/javascript-form-component/blob/main/formComponent/components/modules/fade.js) (Fade effects), [`formComponent/jsonData/inputPhoneSelectPrefix/inputPhoneSelectFlagPrefix.php`](https://github.com/francesca-22/javascript-form-component/blob/main/formComponent/jsonData/inputPhoneSelectPrefix/inputPhoneSelectFlagPrefix.php) (Phone prefix list)
