By default, the label appears above the input element(s), but you may optionally render horizontal (label to the left of the input) at the various standard Bootstrap breakpoints.
You can control the label text size match the size of your form
input(s) via the optional label-size prop. Values can
be 'sm' or 'lg' for small or large
label, respectively. Sizes work for both horizontal and
non-horizontal form groups.
Feel free to nest <b-form-group> components to
produce advanced form layouts and semantic grouping of related
form controls:
