Can I set a "Element attribute" as Parent selector

Hello,

I wonder to know if I Can I set a "Element attribute" as Parent selector, because when I try to set it as Parent for other Selector, I cannot found it !

I m using "Element attribute" to extract categories which in a hover menu, and in every category there is Pagination, and of course the product to scrape.

PS: I think that I can use "Start URL" and put all categories URLs on it, but if there is anyway to do it otherwise.

Thank you
