- Select the Callbacks tab in the Component Browser. The left side of the Callbacks
tab shows a list of supported callback properties. The text field next to each callback
property allows you to specify a name for the callback function. The down-arrow next
to the text field allows you to select a default name in angle brackets <>. If your app
has existing callbacks, the drop-down includes those callbacks. Select an existing
callback when you want multiple UI components to execute the same code.
