Accessibility Compliance Module

Overview

Form Builder:

Each Form.io component is tested for accessibility compliance using standalone applications. To create accessible forms, we offer a form builder that includes only the components that have been revised and designed in compliance with WCAG 2.1 standards.

When building forms leveraging the Form Manager application, the Form Builder will automatically restrict non-accessible components and settings allowing the user to create fully accessible forms.

When leveraging the Developer Portal the following components should not be used when creating fully accessible forms. These components are not included in the Accessibility Compliance Module, and do not meet accessibility-compliant standards or follow best practices in catering to a broader audience engaging your forms:

• Tags

• Address

• Survey

• Tabs

• Data Map

• DataGrid

• EditGrid

• Recaptcha

• Nested Form

• Sketchpad

• Tagpap

• DataTable

• Signature

• Custom

Form rendering module handles the following:

• Screen readers' announcements upon user action

• Focus order/Focus trap/Focus placement

• Dynamic change of aria-attributes

• Validation messages handling

• Special styles for invalid/valid fields

Form.io USWDS template module OR Form.io Bootstrap template module handles the following:

• Proper HTML markup (every form field needs an associated label, correct component structure etc.)

• Aria-attributes such as aria-describedby, aria-labelledby, etc.

• Additional helpful messages for sighted users

• Additional instructions for non-sighted users (e.g. number types, etc.)

• WCAG compliant color contrasts (only applicable for USWDS for now)

Features

1. Accessible Form Manager

2. Accessibility Templates (USWDS)

   • Accessibility templates github path: https://github.com/formio/uswds

     • Provides HTML markup for accessible forms.

3. Accessibility Module

   • Provides overrides for formio.js renderer and builder.

   • Cuts down options within the Form.io Portal Form Builder to avoid components for which accessibility is not supported.

   • Includes Builder markup overrides to make the builder accessible (keyboard accessibility, accessible drag-n-drop functionality, additional screen reader announcements upon user actions).

   • Handles dynamic changes on the form and during building a form.

When customers utilize BOTH USWDS + VPAT for embedded forms within their applications, they receive the following features:

How to Embed Accessible Forms that were built within the Accessible Form Manager Application into customer applications (with accessible templates and VPAT functionality included in the applications):

Repositories used:

1. https://github.com/formio/formio.js

2. https://github.com/formio/uswds

To embed the “https://examples.form.io/example” directly to a website the following code should be used.

<html>
    <head>
        <meta charset="utf-8">
        <link rel="stylesheet" href="https://cdn.form.io/formiojs/formio.full.min.css">
        <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/uswds/2.12.0/css/uswds.min.css">
        <link rel="stylesheet" href="dist/uswds.css">
        <script src="https://cdn.form.io/formiojs/formio.full.min.js"></script>
        <script src="dist/uswds.js"></script>
        <script src="dist/vpat.js"></script>
    </head>
    <body>
        <div id="formio"></div>
        <script type="text/javascript">
            Formio.use(uswds);
            Formio.use(vpat);
            Formio.createForm(document.getElementById('formio'), 'https://examples.form.io/example');
        </script>
    </body>
</html>

Alternative Use Case: Embedding the Accessible Form Builder (commercial not OSS) directly within the customer application:

Repositories used:

1. https://github.com/formio/formio.js

2. https://github.com/formio/uswds

3. https://github.com/formio/vpat

An alternative way to use the Accessible form builder is to embed the Form.io Form Builder within the application using the following code.

<html>
    <head>
        <meta charset="utf-8">
        <link rel="stylesheet" href="https://cdn.form.io/formiojs/formio.full.min.css">
        <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/uswds/2.12.0/css/uswds.min.css">
        <link rel="stylesheet" href="dist/uswds.css">
        <script src="https://cdn.form.io/formiojs/formio.full.min.js"></script>
        <script src="dist/uswds.js"></script>
        <script src="dist/vpat.js"></script>
    </head>
    <body>
        <div id="builder"></div>
        <script type="text/javascript">
            Formio.use(uswds);
            Formio.use(vpat);
            Formio.builder(document.getElementById('builder'));
