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}}
/>
