# Reference lookup

On forms, the reference lookup icon \(\[Omitted image "SearchIconHeisenberg.png"\] Alt text: Core UI reference lookup icon\) appears by editable reference fields. Clicking the reference lookup icon displays a list of records on the referenced table.

When List v3 is enabled, the list appears in a popover. Otherwise, the list appears in a pop-up window.
