When configuring a custom widget on a dashboard within Cisco Secure Firewall Management Center (FMC), it is mandatory to provide a title for the system to display the information correctly. The title helps in identifying and organizing the widget on the dashboard. Steps: * Navigate to the dashboard section in FMC. * Add a new custom widget. * Configure the widget settings and provide a title. * Save and apply the widget to the dashboard. Providing a title ensures that the widget is correctly displayed and easily identifiable on the dashboard.
