Help with link google

Hi, I need help creating a button linked to a google link, button or dropdown system. Ex: link1- www.link1 and link2 - www.link2.

so, in a dropdown system, I would have option 1 and option 2, if I select option 1, I would go to link1 and so on.

in the button system, I would click on one of the buttons, and go to any google link I choose.

Tried to configure but failed, do I need to use some code or something like that? Anyone who can help with screenshots or with the codes (if necessary) that I should use makes it much easier…
