How to add a checkbox field
- In WordPress, go to Smart Add-Ons → Add-On Groups and open a group, or click + Add group.
- Click + Add field.
- Enter a Field label and set Field type to Checkbox (toggle).
- Under Pricing, enter a Fixed price (or choose Percentage of product price) to charge when the box is ticked.
- Choose Quantity pricing: Per product quantity, or Flat fee (once per line item).
- Click Save group, then open a product the group applies to and check the field.
Example: gift wrap as a flat fee
A store adds a checkbox labelled “Add gift wrap” with a Fixed price of 3 and Quantity pricing set to Flat fee (once per line item). A customer buying four mugs with gift wrap pays 3 once, not 12. With Per product quantity the same order would add 12. The price is shown next to the label on the product page automatically.
Checkbox field FAQ
Can the checkbox be ticked by default?
No. A checkbox always starts unticked, so customers opt in to any paid extra themselves.
How do I show another field only when the box is ticked?
On the other field, enable conditional logic and add the rule “Show this field when [your checkbox] Is checked”. This is the usual way to reveal an engraving text field.
Can I use a checkbox for a terms acknowledgement?
Yes. Leave the price at 0 and tick Required field; the product can’t be added to the cart until the box is ticked.
