Am I able to add a drop-down section/page?

Hello! Am I able to add a drop-down section or page to a website? I want people to be able to click a button and fill out a form/questionnaire (similar to the photo I attached) but I do not want it to take up the entire screen. I'd like for them to be able to X it out if needed.

The "Booking" section is what pops up after pressing Book Now but this is a drop-down.

You mean a button float on right of site (We are online) >> Click it >> A form slide from right to left?

No, that's their customer service chat. The section that is labeled "Booking" with the pick up and return dates is what I'm referencing. This isn't a full page, when you click "Book Now" this is what drops down. I linked their website below so you can see what I mean

Click Button > Show Form: You can use Form Block, when you edit form, it has an option to enable popup

To achieve feature similar example site: Pickup Date, Enter address, Promo Code... you will need to hire a coder (it require a lot of code) or you try find a 3rd party services to achieve it.
