2. Fill a PDF Form

PDF forms are categorized into two types: interactive and non-interactive. Interactive PDFs contain fillable fields that allow you to input information directly by selecting the highlighted areas. Non-interactive PDFs, on the other hand, are static documents with pre-printed text and lines that cannot be edited digitally.

Here are how to fill in interactive forms:

Once you open an interactive PDF form, a blue notice will appear as follows, indicating that fillable fields are available.

  • Click on any fillable field and enter the required text.
  • Save the completed form using File > Save or the keyboard shortcut Command + S (Mac).

For PDF forms with non-interactive form fields, the "Form" tab provides tools to fill them directly.

Now, we'll walk you through each form function and step to help you fill out and manage your forms with ease. Let's get started.

2.1 Add a Text field

For creating interactive areas or gathering user input, use the Text Field tool to draw and customize fillable form fields.

To add a fillable text field:

  • Click the "Text Field" icon in the top toolbar.
  • Position your cursor on the form where you want the field.
  • Click and drag to draw a rectangle, defining the field's size.
  • Release the mouse button to create the field.

2.2 Create a Check Box Field

In PDF forms, checkboxes enable users to select one or multiple options.

Step 2: Similar to radio buttons, you can customize the button style and define an export value. Additionally, enabling the "Checkbox is selected by default" option will pre-select the checkbox upon form load.

2.3 Create a Radio Button Field

Radio buttons are typically grouped together, enabling users to select only one option from multiple choices—ideal for scenarios like gender selection or single-answer questions.

Step 1: Select the Radio Button tool and draw the number of buttons you need on the page. If you need to create a group of such buttons, ensure they share the same name. When only one option should be selectable, assign identical names to the buttons.

For a radio button group, all buttons must have the same name, but each requires a unique value.

Step 2: You can modify radio button styles and other properties under the "Options" tab.

Below is a detailed introduction to the specific configurations:

  • RadioButton Style: Controls the visual design of the radio button (circle, square, etc.).
  • Export Value: Specifies the data value transmitted when this particular radio button is chosen.
  • Button is checked by default: If activated, the radio button will be pre-selected upon form opening, while remaining editable by users.
  • Select the button with the same name and option: Radio buttons sharing identical names but distinct export values create an exclusive group permitting only single selection.

2.4 Create a Combo Box Field

2.5 Create a List Box Field

If you need a PDF form field that displays all options while letting users select one or more, a list box is the ideal solution.

Step 1: Click the "Create a Push Button Field" icon at the top, draw to add the button to your form, double-click it, then select the desired action in the “Actions” tab.

Here are the available actions you can choose from:

Step 2: Access the configuration by clicking the "Select Trigger" tab and choosing an appropriate trigger event.

Available trigger options respond to different user interactions:

Mouse Enter: Engages when the mouse pointer moves into and begins hovering over the form field area.

Mouse Exit: Responds when the mouse pointer departs from the form field area.

On Focus: Triggers when the form field becomes the active element (typically occurs when a user clicks into a text input field to begin entering data).
