Select Dropdown - Variants and Overlay

Hey there.
I’m looking for the best way to implement Select components with interactions in Figma prototypes. I work on a design system and am trying to design select components with the dropdowns built in. Has anyone figured out a way to have a dropdown open above all content and change the field to an active state (Doing this part with variants)? We used to have the dropdown tacked on to the bottom of the input. But we ran into issues with the dropdown pushing content down the page and not appearing above other content in the Z-axis.
