Installation

Use the following command to add ngx-malihu-scrollbar library to your package.json file. Note that jQuery will automatically be downloaded as a dependency.

npm install ngx-malihu-scrollbar --save

You will need to add Malihu Custom Scrollbar javascript and css files with jQuery to your application.

If you are using Angular CLI you can follow the example below...

angular.json

"styles": [
  "src/styles.scss",
+ "node_modules/malihu-custom-scrollbar-plugin/jquery.mCustomScrollbar.css"
],
"scripts": [
+ "node_modules/jquery/dist/jquery.min.js",
+ "node_modules/malihu-custom-scrollbar-plugin/jquery.mCustomScrollbar.concat.min.js"
],

tsconfig.app.json

{
  "compilerOptions": {
    ...
    "types": [
+     "jquery",
+     "mcustomscrollbar"
    ]
  },
  ...
}

Usage

You must import MalihuScrollbarModule inside your module to be able to use malihu-scrollbar directive or MalihuScrollbarService.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
+ import { MalihuScrollbarModule } from 'ngx-malihu-scrollbar';

import { HomeComponent } from './home.component';

@NgModule({
  imports: [
    CommonModule,
+   MalihuScrollbarModule.forRoot(),
  ],
  declarations: [HomeComponent],
})

ngx-malihu-scrollbar provides both a directive and a service to apply the custom scrollbar on your HTML element.

For a complete list of available customization options please refer to the original Malihu Custom Scrollbar documentation.

Directive

You can use malihu-scrollbar directive directly on an HTML element and provide plugin options using scrollbarOptions input property.

example.component.ts

public scrollbarOptions = { axis: 'yx', theme: 'minimal-dark' };

example.component.html

<div malihu-scrollbar [scrollbarOptions]="scrollbarOptions">
   Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua...
</div>

Service

Alternatively, you can initialize scrollbar customizations using MalihuScrollbarService by providing either a string selector, a jQuery object or an HTML element along with the scrolling options.

The service also provide access to other Malihu Custom Scrollbar methods such as scrollTo, stop, update, disable and destroy.

constructor(
  private mScrollbarService: MalihuScrollbarService,
) { }

ngAfterViewInit() {
  this.mScrollbarService.initScrollbar('#myElementId', { axis: 'y', theme: 'dark-thick', scrollButtons: { enable: true } });
}

ngOnDestroy() {
  this.mScrollbarService.destroy('#myElementId');
}

FAQ

Can we customize the scrollbars?

Of course, the scrollbars are fully customizable. You can easily clone an existing theme and modify the CSS to apply your own styling. Follow the instructions provided on the original Malihu Custom Scrollbar Plugin documentation for more details.

The "custom-theme" example on the bottom of the demo is a good example of customization where I created a my own "metro" theme.

How can we apply scrollbar customization on the body?

Using MalihuScrollbarService you can target document.body to apply customization to the body scrollbar.

Note that this will automaticaly add some specific CSS to the <body> element that is needed to allow scrollbar customization.

import { MalihuScrollbarService } from 'ngx-malihu-scrollbar';

constructor(
  private mScrollbarService: MalihuScrollbarService,
) { }

ngOnInit() {
  this.mScrollbarService.initScrollbar(document.body, { axis: 'y', theme: 'dark-3' });
}
