☑️Checkbox

Add checkbox inputs to forms in Webstudio.

See MDN: <input type="checkbox">

The Checkbox component creates an HTML checkbox input for boolean selections.

Overview

Checkboxes allow users to select one or more options from a set, or toggle a single option on/off.

Properties

Property	Type	Description
name	string	Form field name
value	string	Value submitted when checked
checked	boolean	Whether the checkbox is checked
required	boolean	Whether selection is required
disabled	boolean	Whether input is disabled
id	string	Unique identifier
class	string	CSS class names

Basic Usage

Single Checkbox

For a single yes/no option:

Label (display: flex, align-items: center, gap: 8px)
├── Checkbox (name: newsletter, value: yes)
└── "Subscribe to newsletter"

Checkbox Group

For multiple selections:

Box
├── Label
│   ├── Checkbox (name: interests, value: design)
│   └── "Design"
├── Label
│   ├── Checkbox (name: interests, value: development)
│   └── "Development"
└── Label
    ├── Checkbox (name: interests, value: marketing)
    └── "Marketing"

When submitted, all checked values are sent with the same name.

Styling Checkboxes

Native Styling

Browser checkboxes can be styled with:

• accent-color: Change the checked color

• width/height: Adjust size

• cursor: pointer: Show clickable cursor

Custom Checkbox

For fully custom checkboxes, consider using the Radix Checkbox component, which provides complete styling control while maintaining accessibility.

Form Submission

Single Checkbox

If checked, sends: name=value If unchecked, nothing is sent

Multiple Checkboxes (same name)

Sends all checked values: interests=design&interests=development

Validation

Required Checkbox

For required checkboxes (like terms acceptance):

Label
├── Checkbox (name: terms, required: true)
└── "I agree to the terms and conditions"

The form won't submit until the checkbox is checked.

Accessibility

1. Always use labels: Associate every checkbox with a label

2. Group related checkboxes: Use fieldset and legend for groups

3. Provide clear labels: Make options self-explanatory

4. Keyboard support: Ensure checkboxes work with Space key

Grouping with Fieldset

Box (role: group)
├── Text (role: legend) → "Notification Preferences"
├── Label
│   ├── Checkbox (name: notify, value: email)
│   └── "Email notifications"
└── Label
    ├── Checkbox (name: notify, value: sms)
    └── "SMS notifications"

States

Style different checkbox states:

State	Description
Unchecked	Default empty state
Checked	Selected state
Disabled	Cannot be interacted with
Focus	Keyboard focus visible
Indeterminate	Partial selection (JavaScript only)

Best Practices

1. Use for multiple selections: Use checkboxes when users can select multiple options

2. Label clickable: Make entire label area clickable

3. Vertical alignment: Stack checkboxes vertically for easier scanning

4. Reasonable defaults: Pre-check options when appropriate

5. Clear labeling: Use positive phrasing (what happens when checked)
