Can i change an filter option to a dropdown menu?

Hi! I am newly here, and I do not know if im posting in the right place, I hope i can get help.
I am working on a website for an electronics store.
Which sells fridges and alot of more stuff, each product we have from different companies.
(for instance : fridges we sell LG,BEKO,SAMSUNG and more)
So under collection tab ( the space with red border) ill be having the options for the type of products, like fridge, TV , washing machine, Coffee machine, and so on.

here comes my question, am i able to create each option in it, when i click it, to open sub menu that shows the company names who sells this product and i pick?
like:
if in collection i have TV option and i click it,
Can a sub menu open under the TV option shows : SAMSUNG ,LG , Haier, Sony.
and then i pick the company and the TV products by this company will be shown?

thank you.
Best Regards.

Take a look at the Cascading Form example. That will give you a good idea how to do what you want.
