How to create custom shapes using template binding in React Diagram

The Syncfusion® React 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:

function App() {
 return (
         <DiagramComponent
           id="container"
           nodes={[{
               id: 'node1',
               offsetX: 100,
               offsetY: 100,
               width: 100,
               height: 100,
             }]}
           nodeTemplate={diagramTemplate.bind(this)}
           getNodeDefaults={(obj) => {
             obj.shape = {type: 'HTML'};
             obj.backgroundColor = '#6BA5D7';
             return obj;
           }}
         >
         </DiagramComponent>
 );
} 

Define the Custom HTML Template:

Implement the nodeTemplate function to define the custom HTML content within the node.

function diagramTemplate() {
 return (
   <div>
     <button onClick={nodeBtnClick}>Button</button>
   </div>
 );
}
