1. From Setup, in the Quick Find box, enter App Builder, then select **Lightning App Builder**.
2. Edit an existing app page, or click **New** to create one.
3. In the Lightning App Builder, add a custom source component to your page.
    
    If you don’t have target components on your page, add those too.
4. Click the source component on the canvas.
5. In the properties pane, click the **Interactions** tab.
6. Under the desired event, click **Add Interaction**.
    
    The properties pane changes to show you the interaction details.
7. Select an interaction.
    
    Currently, the only interaction available is Update Properties.
8. Select the target component for the interaction.
    
    Components are listed with their region location to help you select the correct component when you work on pages with components spread across multiple regions.
    
    ![Interaction details pane](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-extend_click-264-0-0-production-enus/5f7d9219-b7b1-4552-8891-f1aba9b289fc/extend_click/images/di_interaction_details.png)
9. Configure the target component properties.
    
    When you select a target component, its properties appear in the Interaction Details pane. There you define the value that you want each target property to have when the interaction happens. If you leave a target property blank, its value remains unchanged when the event triggers.
    
    To [use an expression to define a target property value](https://help.salesforce.com/s/articleView?id=platform.dynamic_interactions_expressions.htm&release=264.0.0&type=5 "An expression is a small chunk of code that can be evaluated to a value. It can be as literal and simple as 1+1 or a more complex combination of variables, operators, and functions. One expression is supported for Dynamic Interactions in the Lightning App Builder: {!Event.eventPropertyName}. You can use this expression when setting target component property values in the Lightning App Builder UI and in Metadata API. The value of the eventPropertyName part of the expression varies based on which properties the developer makes available for the event in the source component.") dynamically, click ![Expression button icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-extend_click-264-0-0-production-enus/5f7d9219-b7b1-4552-8891-f1aba9b289fc/extend_click/images/di_expression_icon.png).
    
    Checkbox properties have a **No change** option. If you’ve changed the value of a checkbox property, use this option to reset it back to its original value, and to indicate that you want its value to remain unchanged when the event triggers.
10. Save the page.

With Dynamic Interactions, an event occurring in one component on a Lightning page, such as the user clicking an item in a list view, can update other components on the page. Dynamic Interactions lets admins create applications with components that communicate and transform based on user interactions, all in the Lightning App Builder UI. It unlocks capabilities that previously were reserved only for developers.")
