Hi,
I have this code

<s:fileUpload /> <h:commandButton value="Add more file to upload" />

I want each time user press the button one more fileUpload append to page

what is the best way to do that ?

is it better to handle this on client or server ?

is there any component for this purpose?

I'm using Seam 2.2 and Richfaces 3.3

Thanks in advanced
