# Step 6: File Maintenance Field Layout

Preview Mode |

The Preview button is enabled on all panels in the File Maintenance Generator after a Table Name is entered or selected in Step 1: Definition. Once fields are placed in the Layout Grid, use this button to display a preview of the layout of the NOMADS panel or HTML page. The controls will not actually function; however, tabbing through the fields and switching folder tabs (if included) will work.

Prior to completing the File Maintenance Generator, use the Preview button to view results whenever needed; for example, after adjusting the field layout or when visiting previous steps to change settings.

Click the drop-down arrow on the Preview button for more options:

Preview NOMADS Panel | (Available when NOMADS Panel check box is selected for Form Type) Displays a preview of the layout of the NOMADS panel; however, the controls will not actually function.
Preview HTML Page | (Available when HTML Page check box is selected for Form Type) Displays a preview of the layout of the HTML page; however, the controls will not actually function. If the Webster Preview URL has not been defined, a message will display.
Webster Preview URL | Launches a separate window for entering a valid URL, which is required to preview an HTML page created by the File Maintenance Generator. A Web server must be running and pointing to an installation of Webster+. The URL should specify the server and the Port number, separated by a : (colon). Example: localhost:8088/ (indicates that the Web server is running on your local machine on Port 8088)

(The Preview button drop-down options were added in PxPlus 2021.)
