link to an already filtered - filterable portfolio

password is "spiderman" if there is any

I am using DIVI and I like it.

How do create a link to a filtered portfolio... currently it goes to ALL as default or "#"

I was hoping that it was a simple as birdgroupconstruction.com/projects/#national-retail

I found this code in the css area of the site. I am sure I am close to it? National Retail

any would be AWESOME!
