Use Now Assist in UI Builder to simplify the configuration of event handlers. At present, you can configure the following event handlers using Now Assist in UI Builder: Open page or URL, open or close modals, and viewport
load requested.

## Before you begin

Install Creator Pro Plus, which includes the UI generation plugin.

Activate the Event handler generation skill from the Now Assist Admin.

Role required: ui_builder_admin, and now.assist.creator

## Procedure

1. Navigate to AllNow Experience FrameworkUI Builder.
2. Open an experience to work in or create an experience by selecting CreateExperience.  
   For more information, see [Configure how users interact with your applications in UI Builder](https://servicenow-prod.fluidtopics.net/nDWg0NsWQpdF_OppvTVe5g "Learn what an experience is in UI Builder. Understand what an experience contains.").
3. Open or create a page.  
   For more information about how to create a page in UI Builder, see [Create a page in UI Builder](https://servicenow-prod.fluidtopics.net/qg0Cc5eGfpImb71VJtmSew "Create a page in UI Builder for a portal, workspace, or custom application so that you can build a web experience for your users.").
4. Add a component to your page, such as a button.  
   For more information about adding components to a page, see [Add and configure components](https://servicenow-prod.fluidtopics.net/J6n1ilCnrc90JWEGwzeCiA#add-components "Learn how to add components to your page in UI Builder. A page is built by adding components.").
5. To add an event handler to your component's event, go to the configuration panel and select Events.  
   An event handler lets you assign an event to a component. For example, if you add a button component to your page, you want it to perform an action when a user selects it.
6. In the event handler, select Open page or URL and select Continue.  
   The Open page or URL event handler was previously called Link to destination.
7. In the Configure section, select Get Started.
8. In the Generate configuration with Now Assist field, enter a prompt for the action you want to perform (for example, open a specific website) or select an option from the available prompts.  
9. Select the right arrow icon.  
   The prompt is sent to the LLM, which processes the request and provides a response that configures the event handler.
10. Either reject the configurations, or accept and edit the configurations.
11. After you review the changes, select Add.
12. Test the event by selecting Preview in the header and trigger the action.

## Result

The event handler configurations are updated.
