To center form fields
Choose Forms > [desired tool], or select the form tool you used to create the form field on the Form Toolbar.
Select a form field you want to center, or press Shift to select more than one.
Right-click and choose a command from the Center menu. Vertically places the fields midway on the page between the left and right margins. Horizontally places them midway between the top and bottom of the page. Both places them in the middle of the page.
