Checkbox is an extension to standard checkbox element with theming.

import { Checkbox } from 'primereact/checkbox';

Checkbox is used as a controlled input with checked and onChange properties.

<Checkbox onChange={e => setChecked(e.checked)} checked={checked}></Checkbox>

Multiple checkboxes can be grouped together.

<div className="flex flex-wrap justify-content-center gap-3">
    <div className="flex align-items-center">
        <Checkbox inputId="ingredient1" name="pizza" value="Cheese" onChange={onIngredientsChange} checked={ingredients.includes('Cheese')} />
        <label htmlFor="ingredient1" className="ml-2">Cheese</label>
    <div className="flex align-items-center">
        <Checkbox inputId="ingredient2" name="pizza" value="Mushroom" onChange={onIngredientsChange} checked={ingredients.includes('Mushroom')} />
        <label htmlFor="ingredient2" className="ml-2">Mushroom</label>
    <div className="flex align-items-center">
        <Checkbox inputId="ingredient3" name="pizza" value="Pepper" onChange={onIngredientsChange} checked={ingredients.includes('Pepper')} />
        <label htmlFor="ingredient3" className="ml-2">Pepper</label>
    <div className="flex align-items-center">
        <Checkbox inputId="ingredient4" name="pizza" value="Onion" onChange={onIngredientsChange} checked={ingredients.includes('Onion')} />
        <label htmlFor="ingredient4" className="ml-2">Onion</label>

Checkboxes can be generated using a list of values.

{ => {
    return (
        <div key={category.key} className="flex align-items-center">
            <Checkbox inputId={category.key} name="category" value={category} onChange={onCategoryChange} checked={selectedCategories.some((item) => item.key === category.key)} />
            <label htmlFor={category.key} className="ml-2">{}</label>

Invalid state is displayed using the invalid prop to indicate a failed validation. You can use this style when integrating with form validation libraries.

<Checkbox invalid={!checked} onChange={(e) => setChecked(e.checked)} checked={checked}></Checkbox>

Specify the variant property as filled to display the component with a higher visual emphasis than the default outlined style.

<Checkbox onChange={e => setChecked(e.checked)} checked={checked}></Checkbox>

When disabled is present, the element cannot be edited and focused.

<Checkbox checked disabled></Checkbox>

Screen Reader

Checkbox component uses a hidden native checkbox element internally that is only visible to screen readers. Value to describe the component can either be provided via label tag combined with inputId prop or using aria-labelledby, aria-label props.

<label htmlFor="chkbox1">Remember Me</label>
<Checkbox inputId="chkbox1" />

<span id="chkbox2">Remember Me</span>
<Checkbox aria-labelledby="chkbox2" />

<Checkbox aria-label="Remember Me" />
