# A wrapper is an object that holds several components and render them.
|
|
# A component may be any object that responds to `render`.
|
|
# This API allows inputs/components to be easily wrapped, removing the
|
|
# need to modify the code only to wrap input in an extra tag.
|
|
#
|
|
# `Many` represents a wrapper around several components at the same time.
|
|
# It may optionally receive a namespace, allowing it to be configured
|
|
# on demand on input generation.
