Checkbox
Checkbox
A Checkbox is a small square that customers click to select or deselect a value. Customers can pick one, several, or none - it shows a checkmark when selected.
When to use a Checkbox
- Product customization - add-ons like gift wrapping, extra toppings, or scent/flavor options.
- Compliance and agreements - confirm age eligibility, agree to terms, or accept a return policy.
How to add a Checkbox option
Step 1: Add the option
Open 1. Add options, click Add option, tick Checkbox under Choice list on the New options tab, then click Add options.
Step 2: Name it and add values
Enter the Label on product (e.g., "Choose Scent") and add the Option values (e.g., Lavender, Vanilla, Eucalyptus). Tick any options below based on your needs:
- Required field if customers must choose before checking out
- Hide option label to hide the label above the values
Step 3: Save and test
Click Save, then open the product page on your store to check that the Checkbox works correctly.
Option settings
Set only what you need - all of the settings below are optional. In the Option values table, click Columns to show Add-on, Help text, SKU or Quantity for each value:
- Add-on - charge extra for a value (Extra fee, Advanced plan and above) or link it to a Shopify variant (Upsell product, Platinum and above). See Manage add-on (additional fee for option).
- SKU - a SKU for that value. Advanced plan and above. See How does Product Option SKU works?.
- Quantity - let customers choose how many of that value they want. Platinum plan and above. See How to Use the "Quantity" Feature for Options.
Default value
Toggle Default for the value that should be pre-selected when the customer opens the product page. Available on the Advanced plan and above.
How it looks on your storefront:
Help text
Add a short note explaining what to choose, shown as a Tooltip, Below the option title, Beside the option title, or Below the option. Available on the Platinum plan and above.
Example of Help text shown as a Tooltip on the storefront:
Limit how many values can be selected
Set Min and Max to control how many values a customer can pick. Available on the Advanced plan and above. See Limit Min/Max Selectors.
If a customer picks fewer or more values than allowed, OPTIS shows a message below the field.
Show or hide with Visibility (conditional logic)
Show or hide the Checkbox based on another option. Available on the Advanced plan and above. See How to set up Conditional logics?.
Layout
In the Display tab: set Option width (25%, 33%, 50%, 67%, 75% or 100%) to control how much horizontal space the option takes, and Option value orientation (Horizontal or Vertical) to lay the values out in a row or stack them.
