Specifying the display state for an object
You can specify attributes indicating the state of an object, which gives database users visual feedback for actions they take. For example, you can format a button so it displays in a slightly darker color when a user clicks the button, or you can indicate that the current record displays in a contrasting color in List View.
To specify the display state for an object:
In Layout mode, select one or more objects.
See Selecting objects.
Note  To have the active (current) record or alternating records display with a different fill in List View, select the Body part label. The body part is considered to be an object in the following steps.
Click Inspector Inspector button in the layout bar, then click Appearance.
The object type drop-down list (at the top of the Appearance tab) displays the type of the selected object. If you select objects of different types, FileMaker Pro displays Selected Objects.
For objects with several components (for example, portals or slide controls), choose from the object type drop-down list.
Normal or Inactive
The body layout part is viewed in Form View or List View or related records are displayed in the rows of a portal. Setting the Primary state fills the background of the body part or all rows in a portal.
