Adding Multiple Attachments

I want to add a multiple attachment control in my site
There is nothing like multiple attachment control. There is 'File Upload' control and you need to put multiple ones as per need.
 
Either put 3-4 file upload controls by default OR put a button that will add file upload control at runtime. Try out.
 
Though there is a jQuery plugin that allows multi-select of files from a single upload: jQuery Multiple File Upload Plugin[^]
