Checkout billing address same as shipping address

I have a question for when a client is logged in. If in checkout, I don’t want my billing address to be the same as shipping, I have a select input to choose another one. But i want the design to be like the shipping one. To have some elements in a square and select the address you want. Do you know how i can do something like this? I tried inspect that select because firstly i wanted to take the option’s value, but i don’t have any values there. And the text from that option isn’t complete so i can chooose it. Thank you!
