# Configure How Many Checkbox Values Shoppers Can Select

Set minimum and maximum selections on an Infinite Options checkbox field, or make it behave like a single choice, using Additional configuration.

Checkbox fields allow shoppers to select multiple values by default. If you want to require a certain number of selections or limit how many options shoppers can choose, you can adjust the field’s Additional configuration settings.

### Limit Shoppers to One Checkbox Selection

If you want a checkbox field to work like a single-choice option:

1. Open the option field.
2. Scroll down to Optional.
3. Click Additional configuration.
4. Set:
   * Min Selections: `1`
   * Max Selections: `1`

Shoppers will still see the checkbox layout, but they’ll only be able to select one value at a time.

### Allow Multiple Choices With a Limit

You can also use these settings to control any selection range:

* Require shoppers to pick 1 to 3 values:
  * Min Selections: `1`
  * Max Selections: `3`
* Make the field optional, but allow up to 2 choices:
  * Min Selections: `0`
  * Max Selections: `2`

### Prefer a Single-Choice Style?

If shoppers should only choose one option, you can also use a radio button or dropdown field. These field types automatically limit shoppers to one selection and can make the choice clearer.
