{{< /example >}} ## Wrapping Input groups wrap by default via `flex-wrap: wrap` in order to accommodate custom form field validation within an input group. You may disable this with `.flex-nowrap`. {{< example >}}

{{< /example >}} ## Sizing Add the relative form sizing classes to the `.input-group` itself and contents within will automatically resize—no need for repeating the form control size classes on each element. **Sizing on the individual input group elements isn't supported.** {{< example >}}

{{< /example >}} ## Checkboxes and radios Place any checkbox or radio option within an input group's addon instead of text. We recommend adding `.mt-0` to the `.form-check-input` when there's no visible text next to the input. {{< example >}}

{{< /example >}} ## Multiple inputs While multiple ``s are supported visually, validation styles are only available for input groups with a single ``. {{< example >}}
