How to add HTML elements in annotation in JavaScript Diagram?

This article explains how to add HTML elements in annotations in JavaScript Diagram. The JavaScript Diagram component offers template support for annotations. You can define the SVG/HTML content as a string in the annotation's template property.

Here is an example demonstrating how to define a template in a node's annotation. Similarly, you can define it for connectors:

var node = {
id: 'node1',
annotations: [
 {
  template: '<div style="width:100%;height:100%">
             <input type="button" value="Submit">
             </div>', 
 width: 57, height: 25 }]
}

You should specify the width and height for the annotation that renders the HTML template, ensuring it is displayed with the desired dimensions.
