The mode option that allows users to remove portlets added as part of a published dashboard is "Unlocked." When a dashboard is in Unlocked mode, users have the flexibility to add, move, or remove portlets according to their preferences or needs. This mode is designed to provide users with a level of personalization and control over their dashboard layout, ensuring that the information displayed is most relevant to their roles or tasks at hand. Conversely, a Locked dashboard restricts users' ability to modify its configuration, preserving the layout as specified by the administrator or the dashboard publisher. The Unlocked mode is particularly useful in dynamic work environments where individuals require the ability to tailor the information and tools accessible through their dashboards.References:
