=head1 NAME
HTML::FormHandler::Widget::Wrapper::Bootstrap - Twitter Bootstrap 2.0 field wrapper
=head1 VERSION
version 0.40057
=head1 SYNOPSIS
Wrapper to implement Bootstrap 2.0 style form element rendering. This wrapper
does some very specific Bootstrap things, like wrap the form elements
in divs with non-changeable classes. It is not as flexible as the
'Simple' wrapper, but means that you don't have to specify those classes
in your form code.
It wraps form elements with 'control-group' divs, and form 'actions' with
'form-actions' divs. It adds special additional wrappers for checkboxes and radio
buttons, with wrapped labels.
=head1 DESCRIPTION
Tags supported:
label_no_filter -- don't html filter the label
label_after -- useful for putting a colon, or other trailing formatting
before_element -- insert tag before input, outside element's control div
before_element_inside_div -- insert tag before input element, inside control div
input_prepend -- for Bootstrap 'input-prepend' class
input_append -- for Bootstrap 'input-append' class
input_append_button -- 'input-append' with button instead of span
no_errors -- don't append error to field rendering
after_element -- insert tag after input element
