Magento

My client has an ancient site that I’m replacing with a modern Magento setup. Unfortunately, he’s very reluctant to step away from his previous navigation system, so I have to try and replicate it on Magento as closely as possible. I’m having a hard time finding modules that will do that, and I’m a rubbish coder on a setup this complex.

Here’s an image of what he’s looking for

I’d appreciate any suggestions. Thanks in advance.
