umbraco-modals

You generate a modal token, implement an UmbModalExtensionElement using Lit, and register a manifest entry under the modal alias to establish type-safe communication between the caller and the dialog.

You register a custom modal by creating a manifest entry under the modal alias that lazy-loads your UmbModalExtensionElement implementation, matching Umbraco's official extension-type patterns for backoffice registration.

Yes, Umbraco modals support opening via routed deep-links for shareable URLs and navigation flows. You configure this using the modal extension type to route dialogs or sidebars directly.

A modal token is a generated definition for strongly-typed data and return values in Umbraco backoffice modals. It ensures consistent communication between the caller and the modal element during data exchange.

Yes, implementing Umbraco backoffice modals uses TypeScript and Lit to build the UmbModalExtensionElement. This provides the typed token communication and UI rendering required for extension development.

Modal tokens require strict alignment between the generated token, modal element, and manifest entry per Umbraco documentation. Communication is constrained to the predefined typed data and return values established by the token.
