React Diagram - Templates
The Diagram component provides the following properties to create custom shape templates.
- The customShapeTemplate property defines a common template for all shapes in the component.
- The template property defines a template for an individual shape.
Template content must be presented as SVG elements.
In this demo, the customShapeTemplate property adds the 'Show Details' link to a shape. When clicked, it displays a popup window that contains additional information about an employee.
