What is required for a tab to become functional on a dashboard?

For a tab to become functional on a dashboard, at least one widget must be placed on it. Widgets serve as the components that display data, analytics, or visual representations within the dashboard. Without any widgets, the tab would lack interactive elements or content, rendering it ineffective for users looking to analyze or monitor information.

Having at least one widget provides the necessary functionality for users to engage with the data presented. This foundation allows for further enhancements and customization of the dashboard, as users can add multiple widgets, adjust settings, and tailor the information shown according to their needs. Therefore, the presence of a widget is crucial for activating the tab's intended features and purposes, making it an essential requirement for functionality.
