How to Set Custom Tooltip for Nodes in React Diagram?

This article explains how to set a custom tooltip for nodes in React Diagram. In Syncfusion® React Diagram, tooltips provide additional information about diagram elements when hovering over or interacting with them. By default, tooltips display details such as size, position, and angle information while dragging, resizing, or rotating nodes and connectors. This article demonstrates how to customize the tooltip content for nodes and connectors in the diagram.

To customize the tooltip content for each node or connector, assign a value to the tooltip property.

Below is a code example illustrating how to display a custom tooltip with the employee’s name when hovering over an employee image node.

let nodes = [
 {
   id: 'node1',
   offsetX: 250, offsetY: 250,
   height: 100, width: 100,
   shape: {
     type: 'Image',
     source:
       'https://ej2.syncfusion.com/demos/src/diagram/employees/image16.png',
   },
   // Constraints to enable tooltip
   constraints: NodeConstraints.Default | NodeConstraints.Tooltip,
   // Set custom tooltip content
   tooltip: { content: 'John' }
 }
];
