Adding form fields
Use the Prepare Form tool to add form fields. Choose the form field to add from the menu at the center top toolbar. A yellow pop-up box will appear below the form field. First, give the form field a name (example: social security number), check the required field box if this field must be completed by the user and then select the "All Properties" link at the bottom right-hand corner of the pop-up box to open the field’s properties in a dialog box. Add a Tooltip to provide necessary context/instruction for users so they know how to complete the form field.
If form field auto-detection is turned on, Acrobat will automatically detect form fields in a document when using the Prepare Form tool. Review Acrobat's form fields and make edits where need be. Check each automatically added form field to ensure that there is a text label/description (see below to learn more about adding field descriptions).
