When you configure a metadata in Curator System Administrator, you can control the way it looks using the GUI editor.

NOTE: This is available as of Curator System Administrator version 2.

By default, when a metadata is configured, it will not display a large number of options in the GUI.

With an option selected, a description is displayed on the left-hand side and a preview is shown on the right-hand side.

No changes will be finalised here until you click Save.

Multi-select allows you to select multiple buttons at once (select buttons in the layout section as an example).

Height controls give controls more height - this makes the next control flow into the next column.
