______

## 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. 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

Wrap the dropdown’s toggle (your button or link) and the dropdown menu within `.dropdown`, or another element that declares `position: relative;`. Dropdowns can be triggered from `<a>` or `<button>` elements to better fit your potential needs. The examples shown here use semantic `<ul>` elements where appropriate, but custom markup is supported.

##### Regular button

Any single `.btn` can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either `<button>` elements:

###### HTML
```html
<div class="dropdown">
  <button
    class="btn btn-primary dropdown-toggle"
    type="button"
    id="dropdownMenuButton"
    data-mdb-toggle="dropdown"
    aria-expanded="false"
  >
    Dropdown button
  </button>
  <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>
```

_______

##### Link button

And with `<a>` elements:

###### HTML

```html
<div class="dropdown">
  <a
    class="btn btn-primary dropdown-toggle"
    href="#"
    role="button"
    id="dropdownMenuLink"
    data-mdb-toggle="dropdown"
    aria-expanded="false"
  >
    Dropdown link
  </a>

  <ul class="dropdown-menu" aria-labelledby="dropdownMenuLink">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>
```
