# Configure Columns dialog box

The Configure Columns dialog box allows you to hide or unhide the available groups of columns in the Summary View, or individual columns in the Record Listing View and Record Comparison View.

The options that appear in the dialog box depend on the columns that appear in the Data Viewer view. For more information, see Hiding or unhiding columns.

Note: You cannot hide the Subject column.
