In almost all cases you should use unique field names when creating form fields. If you use the same name for a field, like a text field, data typed in the field box is replicated for all fields with the same name. The exception to the rule is when creating check box and radio button fields. If you want one check box or radio button in a group to be unchecked as another check box or radio button is checked, you use the same field name. Both these field types have an option for adding an export value. When you create fields with the same name, you use different export values to distinguish one choice from another.
To add a check box field:
1. Open the PDF in Nitro Pro.
2. On the Forms ribbon, in the Form Fields group, click Check Box.
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:
- If you’re using the Properties context tab, in the More group, click Properties and then Options.
- If you’re using the Properties dialog, click the Options tab.
6. Select Options. Choose a style for the check box appearance from the Check Box Style list. Click in Export Value field and add a value. If you have two fields that you want to use as Yes and No responses, use the same name for the two fields and add an export value of Yes in one field and No in the other field. You can also have the checkbox selected by default via the option Checked by default.
To edit a check box form field:
1. Open the PDF in Nitro Pro.
2. On the Form ribbon, in the Form Fields group, do either of the following:
- Click the field type that corresponds to the field you want to edit
- Click Select Fields
3. Double-click the field to begin editing its attributes
