# Controls

- [grid](/brixxbox-documentation/configuration/app-editor/controls/grid.md): A grid displays a list of records, specified by the sub data source of that control.
- [combobox](/brixxbox-documentation/configuration/app-editor/controls/combobox.md): Comboboxes are often used to refer to header records (an order line record will most likely have a combobox with its order record).
