Basic example

Place one add-on or button on either side of an input. You may also place one on both sides of an input. Remember to place <label>s outside the input group.

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.

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.

Multiple inputs

While multiple <input />s are supported visually, validation styles are only available for input groups with a single <input />.

Multiple addons

Multiple add-ons are supported and can be mixed with checkbox and radio input versions.

Button addons

Buttons can also be places within input groups. This would help trigger action before user input is collected.

Buttons with dropdowns

Similar to the example above, you can place dropdowns as well within input groups.
