How to Restrict Textbox Editing for Group Node in Angular Diagram?

This article explains how to restrict textbox editing for a group node in an Angular Diagram. The Angular Diagram component enables users to edit annotations at runtime, either interactively or through code. To prevent users from modifying annotations, the annotationConstraints property can be utilized.

This property allows control over annotation behavior, such as setting them to read-only. To disable editing, apply the “read-only” constraint to an annotation. This ensures the annotation cannot be altered or edited, even if a user double-clicks a group node.

Below is an example demonstrating how to assign the read-only constraint:

{
      id: 'group',
      children: ['rectangle1', 'rectangle2'],
      style: { fill: 'none', strokeWidth: 0 },
      annotations: [{
          content: 'Group',
          constraints: AnnotationConstraints.ReadOnly,
      }],
}
