...

  imports: [
    ...
    NgxStickySidebarModule
    ...

More info here

Instalation ResizeSensor.js

npm install css-element-queries -S

Add "./node_modules/css-element-queries/src/ResizeSensor.js" to angular.json in section scripts.

Usage

Add stickySidebar directive to element witch will be sticky

<div class="main-content">
    <div stickySidebar
          containerSelector=".main-content"
          innerWrapperSelector=".sidebar__inner">
        <div class="sidebar__inner">
            <!-- Content goes here -->
        </div>
    </div>
    <div class="content">
        <!-- Content goes here -->
    </div>
</div>

Note that inner sidebar wrapper .sidebar__inner is optional but highly recommended, if you don't write it yourself, the script will create one for you under class name inner-wrapper-sticky. but this may cause many problems.

UpdateSticky

updateSticky - subject to force re-calculation of all cached dimensions of sidebar, container and viewport and update position of sidebar according to the new dimensions.

Example

Template:

<div
      stickySidebar
      updateSticky="updateSticky">
</div>

Component:

import {Subject} from 'rxjs/Subject';

export class SomeComponent {
    updateSticky: Subject<boolean> = new Subject();
    updateMethod(){
      this.updateSticky.next(true);
    }
}

Options

All parameters are set through the corresponding attributes. For example:

<div
      stickySidebar
      containerSelector=".main-content"
      innerWrapperSelector=".sidebar__inner">
</div>
