toolbarAllowedItemIdentifiers

toolbarAllowed is a configuration concept used in software with toolbars to define which toolbar actions are permitted in a given context. It functions as a white-list that governs which commands or controls can appear, depending on user role, application state, or installed plugins. By listing allowed action identifiers, developers can tailor the toolbar to the needs and restrictions of different environments while preventing unauthorized or irrelevant options from being shown.

In practice, toolbarAllowed is often represented as a list or set of strings that identify individual actions, such as bold, italic, save, undo, or custom commands provided by plugins. It may appear in configuration files, manifests, or code as a property named toolbarAllowed. The value can be static, determined at install time, or dynamic, driven by user permissions, feature flags, or runtime conditions. Some implementations use a more complex structure, such as a mapping from action IDs to boolean permissions, or integration with an access control system.

The use of toolbarAllowed supports security, usability, and maintainability. It helps prevent the exposure of unsupported or unsafe actions, reduces UI clutter, and simplifies customization for different users or deployments. However, it requires careful maintenance to keep the allowlist aligned with available features and plugins. It may also necessitate server-side validation to ensure that the client-side display rules do not enable disallowed actions, protecting against tampering and ensuring consistency across environments. Overall, toolbarAllowed is a practical tool for controlling toolbar composition in modular and multi-user software.
