How to Show/Hide Annotations at Runtime in React Diagram?

You can control the visibility of annotations by adjusting their visible property. The visible property of an annotation determines whether it is shown or hidden on the React Diagram.

To hide or show annotations at once, you need to loop through each node in the diagram and checks the annotations attached to those nodes. Below is a code example demonstrating how to toggle the visibility of annotations with a button click.

let showNodeAnnotations = true;
function App() {  
 const handleannotation = () => {
   let nodesCollection =  diagramInstance.nodes;
   let visibility = showNodeAnnotations ? false : true;
   nodesCollection.forEach(node => {
     node.annotations.forEach(annotation => {
       annotation.visibility = visibility;
     });
   });
   showNodeAnnotations = !showNodeAnnotations;
 };
