Step 2. With the blank PDF created, navigate to the Tools option from the top left side. Now, from the Tools menu, choose the Form option to open a list of form editing tools.

- Text Field
On selecting this button, you can draw a text box across the form at any particular place. This is typically done to create a text box across a specific field where you want the responder to enter their information. Just click on the "Text Field" icon at the top menu, go to the place where you want to add, hold the left side of your mouse to draw an area for the responder to fill. Release your mouse when it is done.

After adding a text field across your blank PDF, you can manage its size using the dotted lines available around the box. Furthermore, you can also drag and drop the text field to change its position across the PDF form.
When double-clicking the text field, its properties panel appears on the right. There, you can change its general properties, style, and action.

In general properties, you can change the following options:
Name: You can rename the selected text field. If you want multiple text fields to automatically display the same content when one is filled, simply give them the same name. For example, to have the second field automatically fill with the same content as the first, name both fields "Text1".

Tooltip: It’s content that appears when you hover over a text field, helping fillers understand what information to enter.

Form Field: You can enable the "Locked" icon to prevent any changes to the selected text field’s properties, such as its size and position. Additionally, you can adjust the field settings as follows:
- Read Only: Prevents users from entering any information.
- Required: Ensures users must fill out the field before submitting.
- Visible: The field is both viewable and fillable.
- Hidden: The field is not visible to users.
- Visible but does not print: The field is shown on screen but won’t appear in printouts.
- Hidden but printable: The field is not visible on screen but will appear when printed.

Default Value: You can set a default value for the field if the content is fixed and known in advance. Users can still delete the default value and enter their own if needed.

You can also configure the following settings:
- Check Spelling: Enables spell check to verify the accuracy of the filler’s input.
- Multi-line: Allows the filler to enter content across multiple lines if the text exceeds the field size.
- Scroll Long Text: Enables scrolling within the field when the entered text is longer than the visible area.
- Allow Rich Text Formatting: Allows fillers to apply formatting (such as bold or italic) to the input text.
- Limit of Characters: Sets a maximum number of characters allowed in the field.

In the Style section, you can customize the background color of the text field, the text color for user input, font style, font size, and text alignment. You can also resize the text field by adjusting its width and height.

You can also set a specific format for the text field, such as number, percentage, date, time, or other special formats. Once a format is selected, you can customize its related properties. For example, if you choose "Number", you can adjust settings like decimal places, separator style, currency symbol, symbol position, and negative number format.

In some cases, especially with number-formatted fields, you may need to perform calculations. You can do this in the Calculate section, where five options are available: Sum (+), Product (×), Average, Minimum, and Maximum.
For example, if you want to calculate the "Price" by multiplying the "Unit" field by the "Quantity" field, simply click on the "Price" text field, choose Product (×), then select "Unit" and "Quantity" from the popup list. Click anywhere outside the list to save your settings.

Now, when users enter the quantity and unit price, the total price will be automatically calculated and displayed in the designated field based on your settings.

- Radio Button
When you select a single option from multiple choices, a radio button serves best. For this case, access the Radio Button option on the top toolbar to add it to the PDF. If you are creating a group of these buttons, the names should align and should be the same if you need to choose only one option.
When you double-click the button, it will display a Properties panel on the right side, providing the following adjustment capabilities:

Same as text field, it also has the Name Tooltip, and Form Field settings. The functions are the same. The different settings for Radio button are following ones:
- Button Style: Choose from various button styles such as “√”, “X”, “·”, and others to customize the appearance of the selection indicator.
- Radio Button Choice: Enter the choice value here to define what will be recorded when the form is exported. This ensures accurate tracking of user selections.

- Button is checked by default: Pre-selects the radio button when the form opens, but users can still choose another option.
- Same name and choice selected in unison: Radio buttons with the same name and choice value are selected together, keeping them synced across the form.
You can also switch to the style section to customize its border color, background color, and resize it.

- Check Box
A checkbox allows users to select one or more options in a PDF form. To add one, select Check Box from the top toolbar and draw it on the form. Double-click the checkbox to access its properties, including Name, Tooltip, and Form Field settings. Like radio buttons, you can customize the button style and set an export value. You can also enable the "Checked by default" option to pre-select the checkbox.

You can also go to the "Style" section to customize its appearance, like border color, background color, and resize it.

- Dropdown
Using this option, a dropdown menu can be created within the form, giving the responders multiple options to select from. Just click on the "Dropdown" icon at the top, draw to create the dropdown in your PDF form, then, double click to get the properties panel.
You can rename the field, add a tooltip, and adjust the form field settings as needed.
Next, add items to the dropdown list by entering the option label under Item, and an export value if required. Click "+ Add Item" to insert it. Repeat this process for each additional option you want to include.

After adding all the items, you can sort the items by checking "Sort Items". With this option, it will sort by the first letter in the word. If you need to sort manually, you click on the "Three Dots" behind each item to "Move Down" or "Move Up".

You can also have the following options.
- Allow user to enter custom text: Let fillers type their own input instead of selecting from the predefined options.
- Check spelling: Enables spell check on the filler's input.
- Commit selected value immediately: Instantly applies the selected value without requiring the user to click outside the field.
Want to set a default selection? Simply click on the desired item in the Item List section.

To customize the style of the drop-down list, click on Style in the right-side panel. From there, you can change the border color, background color, text color, font style, and size, as well as adjust the size of the drop-down list. You can also set a format and add calculations if needed.

- List Box
If your PDF form requires you to list all options while allowing the responder to select one or more options, a list box is the perfect utility to include. Just click on the "List Box", draw to add the list box in the form, and double click to get the properties panel. Name, add the tooltip, and change the form field settings here.
Same as in the drop-down list, enter your item and export value, and click on the "+ Add Item" to add all your options.

Here, you can also get the following options:
- Sort Items: Automatically sorts the item list alphabetically based on the first letter of each item.
- Multiple Selections: Allows users to select more than one option from the list.

You can customize the appearance by clicking on the Style section. There, you can change the border color, background color, text color, font style, font size, and adjust the size of the field.

Just click on the "Button" icon at the top menu, then, double click on to get the properties panel. Customize its name, tooltip, form field if needs.

In the Layout section, you can choose from options like "Label Only", "Icon Only", "Icon Top, Label Bottom", "Label Top, Icon Bottom", "Icon Left, Label Right", "Label Left, Icon Right", and "Label Over Icon."

After selecting how you want the button text and icon to appear, you can customize them. Enter the button text, and if you’ve chosen a layout that includes an icon, click "+ Add Image" to upload your desired icon.

Same as other options, you can customize its style by clicking on the "Style" option. Here, you can set the color, font style, and resize the button.

When creating an action button, the most important thing is to set the action. Click on the Actions tab, select a trigger. Here you can have the following options.
Mouse Down:
Triggered when the user presses the mouse button down on the form field, but before releasing it.
Mouse Up:
Triggered when the user releases the mouse button after clicking on the field.
Mouse Enter:

Reset a Form: Clears all filled form data.
