5 Mar 202624 minutes to read

Customize the Timeline items by adjusting dot size, connectors, dot borders, dot outer spacing, and more to personalize its appearance. This section explains the available styling options.

Connector styling

Common styling

Apply styles universally to all Timeline item connectors.

var dailyRoutine = [
  { content: 'Eat' },
  { content: 'Code' },
  { content: 'Repeat' }
];

// Initializes the Timeline control
var timeline = new ej.layouts.Timeline({
  items: dailyRoutine,
  cssClass: 'custom-connector'
});

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

    <div id="container" style="height: 250px;">
        <!--Element to render the Timeline control-->
        <div id="timeline"></div>
    </div>

    <style>
        .custom-connector .e-timeline-item.e-connector::after {
            border-color: #f7c867;
            border-width: 1.4px;
        }
    </style>

    <script>
        var ele = document.getElementById('container');
        if (ele) {
            ele.style.visibility = "visible";
        }   
    </script>
    <script src="index.js" type="text/javascript"></script>

}

Individual styling

Apply unique styles to individual connectors to differentiate specific items within the Timeline.

var dailyRoutine = [
  { content: 'Eat', cssClass: 'state-initial' },
  { content: 'Code', cssClass: 'state-intermediate' },
  { content: 'Repeat' }
];

// Initializes the Timeline control
var timeline = new ej.layouts.Timeline({
  items: dailyRoutine,
  cssClass: 'custom-connector'
});

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

Dot styling

Dot color

Modify dot colors to highlight specific Timeline items.

var orderStatus = [
  { content: 'Ordered', cssClass: 'state-completed' },
  { content: 'Shipped', cssClass: 'state-progress' },
  { content: 'Delivered' }
];

// Initializes the Timeline control
var timeline = new ej.layouts.Timeline({

  cssClass: 'dot-color'
});

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

Dot size

var dotSizes = [
  { content: 'Extra Small', cssClass: 'x-small' },
  { content: 'Small', cssClass: 'small' },
  { content: 'Medium', cssClass: 'medium' },
  { content: 'Large', cssClass: 'large' }

  cssClass: 'dot-size'
});

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

Dot shadow

Add shadow effects to Timeline dots to provide a visually engaging appearance by using the --dot-outer-space and --dot-border variables.

var orderStatus = [

];

// Initializes the Timeline control
var timeline = new ej.layouts.Timeline({
  items: orderStatus,

Dot variant

Achieve the desired dot variant by customizing the border, outline and background colors of the Timeline dots.

var dotVariants = [

  { content: 'Flat', cssClass: 'dot-flat' },
  { content: 'Outlined', cssClass: 'dot-outlined' }
];

// Initializes the Timeline control
var timeline = new ej.layouts.Timeline({
  items: dotVariants,
  cssClass: 'dot-variant'
});

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

Dot outline

Add the e-outline class to the Timeline cssClass property to enable the dots to have an outline state.

var orderStatus = [
  { content: 'Shipped' },
  { content: 'Departed' },
  { content: 'Arrived' },
  { content: 'Out for Delivery' }
];

// Initializes the Timeline control
var timeline = new ej.layouts.Timeline({
  items: orderStatus,
  cssClass: 'e-outline'
});

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