I use a small black mini bungee to hold the lid open. The bungee can be attached to the lower track for the storage bin's sliding door but that bit of plastic seems a little fragile, so I attach it to a to a little eye bolt that I installed at the back of the bin. This works well for me. It's easy to use, holds the lid open securely, and can be quickly unhooked and shoved into the storage bin when not in use.
