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.
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.
Add the relative form sizing classes to the <c-input-group> itself
and contents within will automatically resizeāno need for repeating the form control
size classes on each element.
Sizing on the individual input group elements isn't supported.
Place any checkbox or radio option within an input group's addon instead of text.
While multiple <CFormInput>s are supported visually, validation
styles are only available for input groups with a single
cFormControl.
Multiple add-ons are supported and can be mixed with checkbox and radio input versions..
Button add-ons are supported.
