Description

Allows a set of options to be specified using the options attribute of the field's configuration. The set of options is then displayed in one of several different forms:

• radio buttons if input_style => 'long' or input_style => 'medium' and multiple => 0.
• check boxes if input_style => 'long' or input_style => 'medium' and multiple => 1.
• select box if input_style => 'short'.

When input_style => 'long' is used both names and descriptions for each option will be displayed with radio buttons / check boxes. For input_style => 'medium' only names are displayed.

Examples

Most basic example. (Provides options in a select box).

{
    name => 'pedagogic_type',
    type => 'set',
    options => [qw(
        presentation
        activity
        case
        enquiry
        problem
        collaboration
        communication
    )],
}

Provide options as radio buttons.

{
    name => 'event_type',
    type => 'set',
    options => [qw(
        conference
        workshop
        other
    )],
    input_style => 'medium',
}

Provide options as check boxes.

{
    name => 'availability', 
    multiple => 1,
    type => 'set', 
    options => [qw( 
        print 
        electronic 
    )], 
    input_style => 'medium',
}

Provide search form options as select box (rather than check boxes). {

    name => 'pedagogic_type',
    type => 'set',
    options => [qw(
        presentation
        activity
        case
        enquiry
        problem
        collaboration
        communication
    )],
    search_input_style => 'short',
}
