NAME

CGI::Toggle -- Utility methods for collapsible sections

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;

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.

METHODS

($control,$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:

 ;; on

If true, the section will be on (visible) by default. The default is false (collapsed).

 ;; plus_img

URL of the icon to display next to the section title when the section is collapsed. The default is /gbrowse/images/plus.png.

 ;; minus_img

URL of the icon to display next to the section title when the section is expanded.. The default is /gbrowse/images/minus.png.

 ;; override

If false (default), the state of the section will be remembered in a cookie. If true, the initial state will be taken from the on option, ignoring the cookie (which will, however, still be generated).
