Introduction

Salesforce OmniStudio FlexCards are a powerful tool for building dynamic, data-driven user interfaces. They allow developers to create reusable, customizable components that enhance the user experience across various platforms. This advanced tutorial aims to expand your knowledge of FlexCards by exploring features such as selectable items, event handling, embedding in OmniScripts, off-platform deployment, dynamic views, and debugging techniques.

Understanding FlexCard Architecture

FlexCards are built on a JSON-driven metadata architecture stored within business process objects. When activated, they are automatically rendered as Lightning Web Components (LWCs), ensuring high performance and seamless integration within the Salesforce ecosystem.

  • JSON-Driven Metadata: FlexCards use JSON configurations to define their structure, data sources, styling, and behavior.
  • Lightning Web Components (LWCs): Upon activation, FlexCards are compiled into LWCs, leveraging the latest web standards for improved performance.
  • Multilevel Embedded Cards: FlexCards support nesting, allowing you to embed one card within another to create complex, hierarchical UIs.

Advanced Features of FlexCards

Selectable Items and Event Handlers

Selectable items enhance user interactivity by allowing users to select one or more items within a FlexCard. This feature can trigger further actions, such as updating data or navigating to a different component.

  • Single-Select and Multi-Select Modes: Configure FlexCards to allow selection of a single item or multiple items.
  • Event Handling: Use event listeners to perform actions based on user selection without writing custom code.
  • Action Debuggers: Utilize debugging tools to monitor events and data flow for effective troubleshooting.

Embedding FlexCards into OmniScripts

Embedding FlexCards into OmniScripts allows you to create guided, step-by-step processes that enhance user experience.

  • Data Passing: Seamlessly pass data between FlexCards and OmniScripts to maintain context and state.
  • Dynamic Capabilities: Leverage dynamic data and conditional rendering to tailor the user journey.
  • Event Management: Trigger and handle events within OmniScripts based on user interactions with FlexCards.

Deploying FlexCards Off-Platform

FlexCards can be deployed outside of Salesforce using OmniOut, expanding their usability across different platforms.

  • OmniOut: A tool that compiles FlexCards into industry-standard web components.
  • Cross-Platform Deployment: Use FlexCards in any Content Management System (CMS) or web application.
  • Consistency: Maintain consistent UI and functionality across platforms.

Dynamic and Conditional Views

FlexCards support dynamic styling and conditional rendering based on data and user interactions.

  • Conditional Styling: Change styles such as colors, fonts, and visibility based on data conditions.
  • Responsive Design: Create UIs that adapt to different devices and screen sizes.
  • Improved User Experience: Provide visual cues and feedback to enhance usability.

Recursive FlexCards

Recursive FlexCards can load themselves repeatedly to handle hierarchical data structures efficiently.

  • Hierarchical Data Management: Ideal for displaying nested data like organizational charts or category trees.
  • Simplified Configuration: Use a single FlexCard configuration to handle multiple levels of data.
  • Scalability: Easily manage complex data structures without extensive coding.

Debugging and Troubleshooting

Effective debugging tools are essential for developing robust FlexCards.

  • Action Debugger: Monitor events, data flow, and network requests within Salesforce.
  • Browser Developer Tools: Inspect component HTML and CSS to identify and resolve issues.
  • Error Logging: Use console logs and alerts to capture errors during development.

Step-by-Step Guide

This section provides a detailed, step-by-step process to implement advanced FlexCard features.

Step 1: Configuring Selectable Items in FlexCards

Objective: Enable users to select items within a FlexCard and trigger actions based on their selection.

  1. Open FlexCard Designer: Navigate to the FlexCard you wish to configure.
  2. Select the Element: Choose the element (e.g., a field or container) you want to make selectable.
  3. Enable Selection: In the element properties, set Selectability to Single or Multiple.
  4. Configure Actions: Add actions to be triggered upon selection, such as updating data or navigating to another component.
  5. Test the Configuration: Use the Preview feature to ensure the selection and actions work as intended.

Step 2: Embedding FlexCards in OmniScripts

Objective: Integrate FlexCards into an OmniScript to create a guided user experience.

  1. Create an OmniScript: Open OmniScript Designer and start a new OmniScript or edit an existing one.
  2. Add a FlexCard Element: Drag the FlexCard element into your OmniScript flow.
  3. Select the FlexCard: Choose the FlexCard you want to embed from the list of available cards.
  4. Configure Data Passing: Map data between the OmniScript and the FlexCard to maintain context.
  5. Set Up Event Handling: Define events that should be triggered based on user interactions within the FlexCard.
  6. Test the OmniScript: Preview the OmniScript to ensure the FlexCard functions correctly within the flow.

Step 3: Deploying FlexCards Off-Platform with OmniOut

Objective: Compile and deploy FlexCards outside of Salesforce using OmniOut.

  1. Access OmniOut: In Salesforce, navigate to the OmniOut utility.
  2. Select FlexCards to Export: Choose the FlexCards you want to deploy off-platform.
  3. Compile FlexCards: Use OmniOut to compile the selected FlexCards into web components.
  4. Download the Package: Obtain the compiled files needed for deployment.
  5. Integrate into External Platform: Include the compiled FlexCard components into your external CMS or web application.
  6. Test Functionality: Ensure the FlexCards work as expected outside of Salesforce.

Step 4: Implementing Dynamic and Conditional Styling

Objective: Apply styles dynamically based on data conditions to enhance the user interface.

  1. Select the Element: Choose the component you want to style conditionally.
  2. Access Styling Properties: In the properties panel, navigate to the Styles section.
  3. Add a Conditional Style: Define a condition based on data (e.g., {data.Status} == 'Active').
  4. Specify Style Changes: Set the CSS properties that should change when the condition is met (e.g., background color).
  5. Repeat for Multiple Conditions: Add additional conditions as needed for different scenarios.
  6. Preview the FlexCard: Use sample data to test the conditional styling.

Step 5: Creating Recursive FlexCards

Objective: Configure a FlexCard to load recursively for displaying hierarchical data structures.

  1. Design the Parent FlexCard: Create a FlexCard that will serve as the parent.
  2. Add a Child FlexCard Element: Within the parent FlexCard, drag a Child FlexCard element onto the canvas.
  3. Select Self-Reference: Configure the child FlexCard to reference the same FlexCard (recursive loading).
  4. Set Data Source: Ensure your data source includes hierarchical relationships (e.g., parent-child IDs).
  5. Configure Data Mapping: Map the data fields appropriately between parent and child cards.
  6. Test the Recursive Loading: Preview the FlexCard to ensure it displays the hierarchical data correctly.

Step 6: Debugging Techniques

Objective: Utilize debugging tools to identify and resolve issues within your FlexCards.

  1. Use the Action Debugger: In Salesforce, enable the action debugger to monitor events and data flow.
  2. Inspect Network Requests: Use browser developer tools to examine API calls and responses.
  3. Check Console Logs: Look for errors or warnings in the browser console that may indicate issues.
  4. Validate Data Bindings: Ensure that data fields are correctly bound using the appropriate syntax.
  5. Test with Sample Data: Use different data sets to test how the FlexCard behaves under various conditions.
  6. Review CSS and HTML: Inspect the rendered components to verify that styles and structures are applied correctly.
