    config?: { intercept?: boolean, tag?: number | string | symbol }
): void;

Parameters

• event - (required) an event to be fired
• callback - (required) a callback to be performed (the callback arguments will depend on the event to be fired)
• config - (optional) an object that stores the following parameters:

Example

// create Kanban
const board = new kanban.Kanban("#root", {
    columns,
    cards
});
// allow moving cards only into the column with the "done" ID
board.api.intercept("move-card", ({ id, columnId }) => {
    if(columnId !== "done" ){
        return false;
    }
}, {tag: "move"});

Change log: The config.tag and config.intercept parameters were added in v1.7
