Bundle product options

Hi There,

We are trying to find a easy way to offer bundled products on our website and have not been able to find something that will work.

We want to do something like the below:

Say we have a bundle that include 3 products and want to have the bundle itself as a product. Visitors then for example buy the “Digital Bundle” that could include perhaps a tablet cover, a memory card and a usb cable.
we want them to physically choose one tablet cover from say 30 that are available in the “Tablet cover category” on the shop. The same needs to happen with the memory card and usb cable.

Ideally, we want something that picks up that the customer have selected a tablet cover, memory card and USB cable and make it a bundle…

Hope that I am explaining it properly and hope that someone could help with this…
