The Inbox component supports conditional display of notifications using the renderNotification prop. This function receives the full notification object and returns a custom React element. You can use worklow data such as tags, identifiers, data object or notfication severity to control how notifications are desplayed in the notification UI. This lets you create create dynamic, personalized notification UI for your subscribers.

​
Display notifications based on workflow tags

You can conditionally display customized notification based on workflow tags. These tags are defined in your workflow and are accessible via notification.tags property. 
import { Inbox } from '@novu/react';

export default function CustomInbox() {
  
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriber="YOUR_SUBSCRIBER_ID"
      renderNotification={(notification) => {
        // filter based on tags
        if (notification.tags?.includes('custom')) {
          return (
            <div>
              <h3>Custom Notification Subject</h3>
              <p>Custom Notification Body</p>
            </div>
          );
        }
        // default
        return (
          <div>
            <h3>{notification.subject}</h3>
            <p>{notification.body}</p>
          </div>
        );
      }}
    />
  );
}

​
Display notifications based on workflow identifier or name

Each workflow has a name and a unique identifier, accessible through notification.workflow.name and notification.workflow.identifier, respectively. Either property can be used to conditionally render notifications. 
import { Inbox } from '@novu/react';
export default function CutomInbox() {
  
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriber="YOUR_SUBSCRIBER_ID"
      renderNotification={(notification) => {
        // filter based on workflow identifier
        if (notification.workflow?.identifier === 'demo') {
          return (
            <div style={{ backgroundColor: 'blue' }}>
              <h3>{notification.subject}</h3>
              <p>{notification.body}</p>
            </div>
          );
        }
        // filter based on workflow name
        if (notification.workflow?.name === 'Custom') {
          return (
            <div style={{ backgroundColor: 'blue' }}>
              <h3>{notification.subject}</h3>
              <p>{notification.body}</p>
            </div>
          );
        }
        // default
        return (
          <div>
            <h3>{notification.subject}</h3>
            <p>{notification.body}</p>
          </div>
        );
      }}
    />
  );
}

​
Display notifications based on data object

You can also use values from the notification data object to render notifications conditionally. These values are accessible via notification.data and typically contain custom payload fields. 
import { Inbox } from '@novu/react';
export default function CutomInbox() {
  
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriber="YOUR_SUBSCRIBER_ID"
      renderNotification={(notification) => {
       // filter based on data object key
       if (notification.data?.priority) {
        return (
          <div style={{ backgroundColor: 'red' }}>
            <h3>{notification.subject}</h3>
            <p>{notification.body}</p>
          </div>
        );
      }
        // default
        return (
          <div>
            <h3>{notification.subject}</h3>
            <p>{notification.body}</p>
          </div>
        );
      }}
    />
  );
}

​
Display notifications based on notfication severity

You can access the severity field on each notification object. This enables conditional rendering in custom UIs. 
import { Inbox, SeverityLevelEnum } from '@novu/react';
export default function CutomInbox() {
 
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriber="YOUR_SUBSCRIBER_ID"
      renderNotification={(notification) => {
        // render based on severity value
        if (notification.severity === SeverityLevelEnum.HIGH) {
          return (
            <div style={{ backgroundColor: 'red' }}>
              <h3>{notification.subject}</h3>
              <p>{notification.body}</p>
            </div>
          );
        }
        
        return (
           <div>
             <h3>{notification.subject}</h3>
             <p>{notification.body}</p>
           </div>
        );
      }}
    />
  );
}
