The most common field type on PDF forms is the text field. Text fields permit respondents to add alpha text and/or numeric values. You can format text fields in a number of different ways to ensure fields are completed properly. You can add custom format scripts, validate data, assign actions, and perform calculations on text fields.
How to add a text field:
1. Open the PDF in Nitro Pro.
2. On the Forms ribbon, in the Form Fields group, click Text Field.
3. On the page, drag the pointer where you want the field to appear.
4. Double-click or right-click on the field and do one of the following (depending on your preferences):
- In the Properties context tab, name the field and set its appearance settings.
- In the Properties dialog, name the field and set its appearance settings.
5. Do either of the following:

6. Click Alignment and select from drop down menu items text alignment for left, center, or right.
7. Add text in the Default Value box if you want text to appear as a default for the field. Something like a zip code or country might be used where most of your respondents are likely to come from the area you add for the default text
