Installation

npm install react-input-checkbox --save

It is necessary to make sure you include component base styles

import 'react-input-checkbox/lib/react-input-checkbox.min.css';

And then use as any other React component

import { Checkbox } from 'react-input-checkbox';

export const FancyCheckbox = props => (
    <Checkbox theme="fancy-checkbox"
        disabled={props.disabled}
        value={props.value}
        onChange={props.onChange}>
);

Usage

Props

children: React.ReactNode

Node that will be placed near checkbox as a label.

disabled : Boolean

Optional, default value is false

Flag for making checkbox disabled.

indeterminate : Boolean

Optional, default value is false

Visual only state of checkbox which is still either checked or unchecked as a state. If you want tot use it, you must create visual styles for that state, because it is not provided by default.

Note: if prop value is true indeterminate state will be ignored

modification : String

Optional, default value is null

CSS class for modification. Good to change color of checkbox, for example.

Note: check material-checkbox for example of changing color without changing the theme

onChange : (event: SyntheticEvent) => void

Callback which will be called any time the input value changes.

theme: String

Optional, default value is null

Class name prefix for your css styles for checkbox

value: Boolean

A value for the checkbox.

Style template

You can use any styles to checkboxes. Here is simple CSS template, that you can copy and paste to your project, just replace %your_style_prefix% with prefix that you will pass to theme prop:

.%your_style_prefix% {
    /* Common styles for the checkbox */
    /* Most likely you will customize left padding here */
}
.%your_style_prefix%__image {
    /* Default state of the checkbox image */
    /* Right place to size, background-image of unchecked state */
}
.%your_style_prefix%__label {
    /* Label styles (font styles mostly) */
}

/* Some states of checkbox image */
.%your_style_prefix%__input:focus + .%your_style_prefix%__image {
    /* Focused and unchecked */
}
.%your_style_prefix%__input:disabled + .%your_style_prefix%__image {
    /* Disabled and unchecked */
}
.%your_style_prefix%__input:checked + .%your_style_prefix%__image {
    /* Checked */
}
.%your_style_prefix%__input:checked:focus + .%your_style_prefix%__image {
    /* Focused and checked */
}
.%your_style_prefix%__input:checked:disabled + .%your_style_prefix%__image {
    /* Disabled and checked */
}

/* Additional indeterminate states */
.%your_style_prefix%__input_indeterminate + .%your_style_prefix%__image {
    /* Marks as indeterminate */
}
.%your_style_prefix%__input_indeterminate:focus + .%your_style_prefix%__image {
    /* Indeterminate and focused */
}
.%your_style_prefix%__input_indeterminate:disabled + .%your_style_prefix%__image {
    /* Indeterminate and disabled */
}
