Interesting navigation, wasn’t expecting it to open the left. Also I would recommend adding &parentClass and an active state to that Wayfinder call, right now it’s mystery meat navigation. Well, technically speaking all drop-downs are mystery meat, but that’s another story. Same thing with the side-nav on the lower level landing pages, hard to determine what section you’ll be in.
For the NIOSH page, I’m not too sure what all there is to it. How would these "methods" normally be arranged if they were in a pamphlet or something? Could you split up the pieces of a "method" into multiple select boxes to delineate a given "method". Something like using the fields below to narrow a search down.
- Flow Rate
- Sampler
- Configuration
Nice clean design though, definitely on the right track, keep up the good work!
