On Drill Down

Last updated 9/04/2026

Overview​

The On Drill Down event is a client-side event that executes when a user clicks the Down button on a parent menu. This allows the application to run logic before navigating to the next level of the menu.

How it Works​

When a user clickes the Down button:

  1. The On Drill Down event executes immediately on the client-side.
  2. Any logic associated with the event executes before the sub-menu is displayed.
  3. You can allow the drill down to proceed or stop it based on conditions.

Use Cases​

  • Control access to certain menu levels based on conditions
  • Prevent navigation if required criteria are not met
  • Trigger UI changes before opening a sub-menu
  • Run client-side checks before allowing deeper navigation

Example​

This function executes when the Down button is clicked and shows a message in the UI.
JavaScript
Show message on drill down
function InvestmentAnalysis(five, context, result) {
    five.showMessage('View your current holding and investment!');
    return five.success(result);
}
