In addition to the properties listed under each component on the Input Types page every bootstrap input component can receive the following bootstrap-specific settings (the values here are the defaults):
<Input name="example"
{/* Bootstrap Grid Sizes */}
xs={12}
sm={undefined}
md={undefined}
lg={undefined}
{/* Bootstrap Grid Offsets */}
xsOffset={undefined}
smOffset={undefined}
mdOffset={undefined}
lgOffset={undefined}
{/* Block changes inputs with layout: "horizontal" to use the full width of
* their container and disables the label. */}
block={false}
{/* Label width for horizontal labels */}
labelWidth={{xs: 12, sm: 2}}
/>
