dialogkomponent

A dialogkomponent, or dialog component in English, is a user interface element designed to present information or request input in a focused overlay that interrupts the main content. It is typically used to convey messages, gather user decisions, or collect data without navigating away from the current view.

Dialog components can be modal or modeless. A modal dialog prevents interaction with the underlying interface until it is dismissed, while a modeless dialog allows continuing work with the underlying content. They usually appear above the main content with an overlay that dims or blocks the background.

Common features include a title, a content area, and an action area containing buttons or controls. Some dialogs include form fields, validation feedback, or dynamic content. They are often sized to fit their content and are designed to be responsive across devices.

Accessibility is a central concern. Dialog components should use appropriate ARIA roles (such as role="dialog" or role="alertdialog"), provide aria-labelledby and aria-describedby references, manage focus when opened, and trap focus within the dialog while it is active. Keyboard interactions typically include Esc to close and Tab navigation to cycle through focusable elements.

API and implementation considerations vary by framework but generally include properties or slots for open/visible state, title, content, and actions, as well as callbacks or events for onClose or onConfirm. They may be composed as standalone components or as part of a larger UI library.

Common use cases include alerts, confirmations, prompts, and lightweight forms. Dialog components are ubiquitous across web, mobile, and desktop UI toolkits, with many frameworks offering built-in or easily extensible dialog primitives.
