Showing and hiding graphic form fields
Form fields can include both graphics and text.You can use buttons, links, bookmarks, and
page actions to show or hide a form field. By alternately showing and hiding a graphic
form field, you can create interesting visual effects within a document. For example, when
you move a cursor over a city on a map, a detail map of the city could be displayed. When
the cursor moves away from the city, the detail map could disappear.
To create the effect of showing and hiding a graphic form field, you first specify a graphic
element for the button that will be shown and hidden. Next, you create a second button
to activate the Show-Hide Field action.You do not assign an icon for the appearance of the
second button. Instead, you assign actions to occur when the mouse enters and exits the
field border. For more information, see
“Setting appearance options” on page 151
and
“Setting action options” on page 152
