Hi abhi3q,

If you have a collection of byte[], you can just use FileDownload.save(...) to trigger a download. You just need to register a listener or a command to trigger it.

Make a ListModel of your own object containing the file name and the byte[] content. Use either children binding or ZK8 forEach shadow elements to instantiate a "click here to download" template using that ListModel. Register a click listener or a command onClick (depending on whether you are using MVC or MVVM). When you receive the click event, retrieve the data (listener) or pass the target object as parameter (command), then use FileDownload.save(...) to pass your byte[] content to download. https://www.zkoss.org/wiki/ZKComponentReference/Essential_Components/Filedownload
