umbraco-entity-bulk-actions

To add Umbraco backoffice entity bulk actions, you register a manifest entry defining the action type, alias, and icon, then implement a class extending UmbEntityBulkActionBase. This class uses the selected item identifiers to execute the batch operation across your chosen document, media, or member collections.

Umbraco entity bulk actions allow editors to apply a single operation to multiple selected items simultaneously via the backoffice toolbar. Use them when users need toolbar-driven batch processing within custom editor workflows for document, media, or member collections.

You restrict bulk actions to specific Umbraco collection types by applying conditions in the manifest registration. These conditions control collection-scoped visibility, ensuring the action only appears for designated document, media, or member collections.

Yes, you can use the Umbraco extension registry to create custom bulk operations for media collections. The process involves registering a doc-aligned manifest entry and creating an action class extending UmbEntityBulkActionBase to process selected media item identifiers.

You process selected item identifiers in an Umbraco bulk action class by iterating over the this.selection array within your UmbEntityBulkActionBase implementation. This approach runs batch logic per item and supports optional repository-driven processing.
