Select more than one attribute in frontend.

Hi,
I have some products were you can chose multiple accessoires for one product.
Fx. A house is the product, and in the attribute you can choose, doors, windows, roof, etc.

If I make an attribute now, I can only select one of the attributes.

Is there a build-in funktion or is there an add-in  ( I´m using 8.0.4 )

Update : 

I did not solve the problem, but insted found an add-on that could do what I needed it to do.
