Persistence in Angular Kanban component

27 Apr 20242 minutes to read

State persistence refers to the Kanban state maintained in the browser’s localStorage even if the browser is refreshed or if you move to the next page within the browser.

State persistence stores Kanban datasource, column and swimlane expand/collapse state in the local storage when the enablePersistence is defined as true.
