I want to make a complicated symbology for my layer. Now it's categorized on column use and I want to add a term "If use=street, different symbology to lamp_type column (H=(x),L=(y) and otheres=(z)"

(x) (y) and (z) are symbols

I mean by that, that categorized symbology has another categorized symbology in it

does someone knows about a code that could do this job for me?

Thanks a lot!!

I want to make a complicated symbology for my layer. Now it's categorized on column use and I want to add a term "If use=street, different symbology to lamp_type column (H=(x),L=(y) and others=(z)"

I have two relevant columns one is "use" which contains [road, street, etc.] and the other is "lamp_type" which contains words like [HPS,LED,MH] etc. I need to make special symbology for every item in "use" and if the "use" is "street" I need to make special symbology for every item in "lamp_type"

How can I set up symbology this way?
