      • duration (default: 400)
        Type: Number or String
        A string or number determining how long the animation will run. The strings "fast" and "slow" can be supplied to indicate durations of 200 and 600 milliseconds, respectively. The number type indicates the duration in milliseconds.

Very useful when trying to visualize interaction between two elements.

The transfer element itself has the class ui-effects-transfer, and needs to be styled by you, for example by adding a background or border.


Clicking on the green element transfers to the other.
