Slate - Creating a drop down search menu

Hello! How would one create a drop down search menu to query specific objects or all objects within the Palantir stack? Someone mentioned a Compass API in a Stack post?

Do you want to have a list of all objects of a single object type in your dropdown?
You could simply create an object set under the platform tab, and use it to populate the dropdown.

If you meant listing object types, then you could use this object type endpoint.
