## What is the Bootstrap Radio?

A Radio Button is a component used to allow a user to make a single choice among a number of options (whereas [Checkboxes](https://mdbootstrap.com/docs/standard/forms/checkbox/) are used for selecting multiple options).

______

## Installation

#### Manual installation (zip package)

To take advantage of  our Bootstrap images component and use them in your project, you first need to install the [MDB 5 Free package](https://mdbootstrap.com/docs/standard/getting-started/installation/#section-manual-installation)

_______

#### MDB CLI

Watch our [**Quick Start Tutorial**](https://mdbootstrap.com/docs/standard/getting-started/quick-start/) to discover and use the full potential of MDB 5 and MDB CLI

_______

#### NPM

###### Prerequisites

Before starting the project make sure to install [Node LTS (12.x.x recommended)](https://nodejs.org/en/).

###### Installation

To install MDB UI KIT in your project easily type the following command in the terminal:
```terminal
npm i mdb-ui-kit 
```

###### Importing JS modules

You can import the entire library or just individual modules:
```terminal
import * as mdb from 'mdb-ui-kit'; // lib
import { Input } from 'mdb-ui-kit'; // module 
```

###### Importing CSS file

To import MDB stylesheet please use the following syntax:
```terminal
@import '~mdb-ui-kit/css/mdb.min.css'; 
```

###### Importing SCSS modules

You can also import individual SCSS modules. To do it properly, we recommend to copy them from the node_modules/mdb-ui-kit/src/scss location directly to your project and import in the same way as CSS files.

###### Webpack integration

You can significantly speed up the process of creating a new project based on Webpack using our [Starter](https://github.com/mdbootstrap/mdb-webpack-starter).

__________

#### CDN

Installation via CDN is one of the easiest methods of integrating MDB UI KIT with your project. Just copy the latest compiled JS script tag and CSS link tag from [cdnjs](https://cdnjs.com/libraries/mdb-ui-kit) to the application.

Don't forget to add also Font Awesome and Roboto font if you need it. Here's an example code:

###### CSS

```css
<!-- Font Awesome -->
<link
  href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
  rel="stylesheet"
/>
<!-- Google Fonts -->
<link
  href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap"
  rel="stylesheet"
/>
<!-- MDB -->
<link
  href="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.css"
  rel="stylesheet"
/>
```


###### JS

```javascript
<!-- MDB -->
<script
  type="text/javascript"
  src="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.js"
></script>
```

## Customization

##### Basic example

Browser default checkboxes and radios are replaced with the help of `.form-check`, a series of classes for both input types that improves the layout and behavior of their HTML elements, that provide greater customization and cross browser consistency. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.

Structurally, our `<input>`s and `<label>`s are sibling elements as opposed to an `<input>` within a `<label>`. This is slightly more verbose as you must specify `id` and `for` attributes to relate the `<input>` and `<label>`.

We use the sibling selector (`~`) for all our `<input>` states, like `:checked` or `:disabled`. When combined with the `.form-check-label` class, we can easily style the text for each item based on the `<input>`'s state.


###### HTML

```html
<!-- Default radio -->
<div class="form-check">
  <input
    class="form-check-input"
    type="radio"
    name="flexRadioDefault"
    id="flexRadioDefault1"
  />
  <label class="form-check-label" for="flexRadioDefault1"> Default radio </label>
</div>

<!-- Default checked radio -->
<div class="form-check">
  <input
    class="form-check-input"
    type="radio"
    name="flexRadioDefault"
    id="flexRadioDefault2"
    checked
  />
  <label class="form-check-label" for="flexRadioDefault2"> Default checked radio </label>
</div>
```

##### Disabled

Add the `disabled` attribute and the associated `<label>`s are automatically styled to match with a lighter color to help indicate the input’s state.

###### HTML
```html
<div class="form-check">
  <input
    class="form-check-input"
    type="radio"
    name="flexRadioDisabled"
    id="flexRadioDisabled"
    disabled
  />
  <label class="form-check-label" for="flexRadioDisabled"> Disabled radio </label>
</div>

<div class="form-check">
  <input
    class="form-check-input"
    type="radio"
    name="flexRadioDisabled"
    id="flexRadioCheckedDisabled"
    checked
    disabled
  />
  <label class="form-check-label" for="flexRadioCheckedDisabled">
    Disabled checked radio
  </label>
</div>
```
