 | AllowedDocTypes | String[] | An array of doc type aliases of which should be allowed to be selected in the grid editor. Strings can be REGEX patterns to allow matching groups of doc types in a single entry. e.g. "Widget$" will match all doc types with an alias ending in "Widget". However if a single doc type is matched, (aka **Single Doc Type Mode**), then doc type selection stage (in the DTGE panel) will be skipped. Note, your document type must be an Element type, in order to be usable in DTGE. |
 | NameTemplate    | String   | Allows using any of the doctype's property values in the name/label: {{propertyAlias}} |
 | EnablePreview   | Boolean  | Enables rendering a preview of the grid cell in the grid editor. |
-| Size            | String   | Define the size of the grid editor dialog. You can write `large`, `medium` or `small`. If no size is set, the grid editor dialog will be small. Note, the medium size requires a minimum Umbraco version of 8.3 |
