Creating combo box fields

Combo Boxes provide users a drop down menu. Only a single response can be selected from the menu. You add menu topics for combo boxes in the Options category in the Form Properties.

To create a combo box field:

1. Select the Combo Box tool from the Nitro PDF Professional toolbar.
2. Drag open a rectangle where you want the Combo Box to appear.
3. Name the field and assign appearance settings.
4. Select Options. Click in the Item field and enter a name in the text box. Click the Add button to add the text to the items list. Type an export value in the Export Value text box. Continue adding items following the same steps.
5. Click the Sort Items check box if you want the list sorted in alphabetica order. Select items in the list and click the Down/Up buttons to rearrange the items in the list manually. Select an item and click Delete to remove it from the list.
6. If you want a user to type an item instead of choosing from the list, click the Allow user to enter custom text check box.
7. Format. If you want a format other than text, such as a date or custom format, choose an option from the Select format category drop down menu.
8. Validation. If you want the field data to be validated, you need to know JavaScript. Check Run custom validation script and type the JavaScript code to validate the field data.
9. Calculate. If the field is to be calculated, check an option for calculating data.

Tip: To set the default selecting from the combo box appearance, click the item in the list you want to be shown in the menu before leaving the Form Properties. If you want an empty field to appear as the default list selection, add a space or dashed line in the item text box and select it before leaving the Form Properties.
