# Checkbox Fields

> Learn how to add and configure single Checkbox questions in your form.

The **Checkbox** field allows you to add a single, isolated checkbox to your form. This is perfect for capturing isolated responses where a user either needs to check a box or leave it blank, such as agreeing to terms and conditions or opting into a specific newsletter.

## Adding a Checkbox Field

To add this field type to your form:

<Steps>
  <Step title="Add Field">
    Click the **+ Add Field** button within your form builder canvas.
  </Step>

  <Step title="Select Field Type">
    In the pop-up menu, under the "Choice" category, select **Checkbox**.
  </Step>
</Steps>

## Field Settings

Once the checkbox is added to your canvas, selecting it will open its configuration settings in the right-hand panel.

### General Settings

* **Question:** Enter the internal name or prompt for your checkbox question here.
* **Default Checked:** Toggle this on if you want the box to be pre-selected when the user views the form. If enabled, the user will have to manually uncheck it to opt out.
* **Required:** Toggle this on if the user must check the box before they are allowed to submit the form.

### Design Settings

These options control the visual appearance of your checkbox container.

* **Minimal Style:** Toggle this on to display a simple, standard bare checkbox without any surrounding container styling.
* **Fill Background:** Choose whether the checkbox has a solid background color behind it.
* **Stack Direction:** Control whether the field aligns vertically or horizontally.
* **Alignment:** Choose to align the checkbox field to the Left, Center, or Right.

### Checkbox Settings

* **Checkbox Text:** This is the specific text that will appear directly next to the checkbox.
  * *Note: If you leave this field completely empty, the form will automatically use whatever text you entered in the "Question" field at the top of the settings panel.*

### Klaviyo Settings

* **Property Name:** This dictates the exact custom property name where the user's response will be saved inside your connected Klaviyo account.
