What is Bootstrap Scrollspy?
Using this component you can highlight where the user is on a page by updating links in navigation based on scroll position. Works perafectly with smooth scroll.
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
MDB CLI
Watch our Quick Start Tutorial 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).
Installation
To install MDB UI KIT in your project easily type the following command in the terminal:
npm i mdb-ui-kit
Importing JS modules
You can import the entire library or just individual modules:
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:
@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.
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 to the application.
Don't forget to add also Font Awesome and Roboto font if you need. Here's an example code:
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
<!-- MDB -->
<script
type="text/javascript"
src="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.js"
></script>
How it works
Scrollspy has a few requirements to function properly:
- It must be used on a Bootstrap nav component or list group.
- Scrollspy requires position: relative; on the element youβre spying on, usually the
<body>
. - When spying on elements other than the
<body>
, be sure to have aheight
set andoverflow-y: scroll;
applied. - Anchors (
<a>
) are required and must point to an element with thatid
.
When successfully implemented, your nav or list group will update accordingly, moving the .active
class from one item to the next based on their associated targets.
