How to add HTML elements in annotation using Vue Diagram?

This article explains how to add HTML elements in annotations using Vue Diagram. The 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 using Vue Diagram. Similarly, you can define it for connectors:

let nodes = [{
id: 'node1',
// Position of the node
offsetX: 100,
offsetY: 100,
// Size of the node
width: 100,
height: 100,
style: {
  fill: '#6BA5D7',
  strokeColor: 'white'
},
// Create an input button for annotation
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.

Refer to the sample to set the template for annotation as follows.
