How to Create Custom Using Template Binding in JavaScript Diagram?

The Syncfusion® JavaScript Diagram supports rendering custom HTML content within nodes using template binding. This allows you to create nodes with dynamic HTML elements such as buttons, forms, or other content.

To define a node with custom HTML content, set the shape property of the node to HTML. Specify the template content using the nodeTemplate function. Here’s how:

let diagram = new Diagram({
   width: '100%',
   height: '550px',
   nodeTemplate: '#nodetemplate', // Referencing the template by its ID
   nodes: [{
       id: 'node1',
       offsetX: 100,
       offsetY: 100,
       width: 100,
       height: 100,
   }],
   getNodeDefaults: (obj) => {
       obj.shape = { type: 'HTML' }; // Setting the shape type to HTML
       obj.backgroundColor = '#6BA5D7'
       return obj;
   }

});
diagram.appendTo('#element'); 

Define the Custom HTML Template:

You can define your custom HTML content inside a <script> tag with a unique id, which will be referenced in the nodeTemplate property of the diagram.

<script id="nodetemplate" type="text/x-template">
     <div>
     <button onclick="nodeBtnClick(event)">Button</button>
     </div>
</script>
