Reverse in EJ2 TypeScript Timeline control

26 Feb 20252 minutes to read

You can display the Timeline items in reverse order for different alignments by using the reverse property. This feature provides adaptability and enhances user interaction.

import { Timeline, TimelineItemModel } from '@syncfusion/ej2-layouts';

const careerProgress: TimelineItemModel[] = [
  { content: 'June 2022', oppositeContent: 'Graduated \n Bachelors in Computer Engineering' },
  { content: 'Aug 2022', oppositeContent: 'Software Engineering Internship \n ABC Software and Technology' },
  { content: 'Feb 2023', oppositeContent: 'Associate Software Engineer \n ABC Software and Technology' },
  { content: 'Mar 2024', oppositeContent: 'Software Level 1 Engineer \n XYZ Solutions' },
];

// Initializes the Timeline control
let timeline: Timeline = new Timeline({
  items: careerProgress,
  reverse: true,
  align: 'before'
});

// Render initialized Timeline.
timeline.appendTo("#timeline");
