# How to use Checkbox Input in Optiontics

## **Overview**

The Checkbox field lets customers select multiple options from a list on a WooCommerce product. Each checked choice adds to — or subtracts from — the price, can show an image, and can carry a per-choice quantity. It's the go-to field for add-ons, extras, and bundles.

## **Use Cases:**

- **Build Your Own" Gift Baskets / Boxes:** Let users check off multiple treats to include (e.g., [x] Dark Chocolate, [x] Roasted Almonds, [ ] Vanilla Caramels).
- **Hardware / PC Upgrades:** Upgrading a device with multiple accessories (e.g., [x] Include Wireless Mouse, [x] Include Laptop Sleeve, [ ] Include Extra Charger).
- **Pizza / Food Toppings:** Selecting multiple ingredients for a custom dish.

### **Step 1: Add the Checkbox Field**

1. Go to **Optiontics → Add-ons** and edit or create an add-on form.
2. Drag the **Checkbox** block from the toolbox onto the canvas.
3. Select the block to open its settings on the right.

### **Step 2: Add and Price Your Choices**

Add one choice per option customers can check. For each choice set:

1. **Label** — text shown next to the box (e.g. "Extra Cheese").
2. **Price** — amount added when checked. Enter a negative value to subtract.
3. **Price type** — **Fixed** (flat amount) or **Percentage** of the product base price.
4. **Default** — mark any choices that should start checked.
5. **Image** (optional) — a thumbnail shown with the choice.

### **Step 3: Adjust Field Settings**

- **Title** / **Hide title** / **Description** — control the heading and helper text.
- **Required** — at least one box must be checked before add to cart.
- **Columns** — lay choices out in 1–N columns.
- **Quantity** — enable a per-choice quantity input and set **Min** and **Max**.
- **Show sale price** — display the discounted choice price when one is set.

### **Step 4: Save and Preview**

1. Click **Save**.
2. Assign the add-on to a product (or category).
3. Open the product page — each checked box updates the total live and carries through to cart and checkout.

## **Frequently Asked Questions (FAQ)**

| **Q1: Can customers pick more than one option?**Yes — that's the point. Checkbox is multi-select, so customers can check as many choices as you offer. |
| --- |

| **Q2: Can I charge per quantity of an add-on?**Yes. Enable **Quantity** on the field and set **Min** and **Max** — the checked choice price is multiplied by the quantity the customer enters. |
| --- |

| **Q3: How do I force at least one selection?**Enable **Required** on the field. The customer can't add to cart until at least one box is checked. |

### **Conclusion**

Use the Checkbox field whenever customers should choose more than one option. With per-choice pricing, optional images, column layout, and quantity, it's the go-to field for extras and add-on bundles.
