=head1 NAME
CGI::Toggle -- Utility methods for collapsible sections
=head1 SYNOPSIS
use CGI ':standard';
use CGI::Toggle
print header(),
start_html('Toggle Test'),
h1("Toggle Test"),
toggle_section({on=>1},p('This section is on by default'),
toggle_section({on=>0},p('This section is off by default'),
toggle_section({plus_img=>'/icons/open.png',
minus_img=>'/icons/close.png'},
p('This section has custom open and close icons.')),
hr,
end_html;
=head1 DESCRIPTION
This package adds JavaScript-based support for collapsible sections by
adding a single new function toggle_section().
It overrides the CGI start_html() method, so CGI must be imported
before bringing this module in.
=head2 METHODS
=over 4
=item ($control,$content) = toggle_section([\%options],$section_title=>@section_content)
This method takes an optional \%options hashref, a section title and
one or more strings containing the section content and returns a list
of HTML fragments corresponding to the control link and the content.
In a scalar context the control and content will be concatenated
together.
The option keys are as follows:
=over 4
=item b<on>
If true, the section will be on (visible) by default. The default is
false (collapsed).
=item b<plus_img>
URL of the icon to display next to the section title when the section
is collapsed. The default is /gbrowse2/images/plus.png.
=item b<minus_img>
URL of the icon to display next to the section title when the section
is expanded.. The default is /gbrowse2/images/minus.png.
=item b<override>
If false (default), the state of the section will be remembered in a
session variable. If true, the initial state will be taken from the
b<on> option, ignoring the session.
