NAME

Spreadsheet::HTML::Presets::List - Generate <select>, <ol> and <ul> lists.

DESCRIPTION

This is a container for Spreadsheet::HTML preset methods. These methods are not meant to be called from this package. Instead, use the Spreadsheet::HTML interface:

use Spreadsheet::HTML;
my $generator = Spreadsheet::HTML->new( data => \@data );
print $generator->list( ordered => 1 );
print $generator->select( values => 1, placeholder => 'Pick one' );

# or
use Spreadsheet::HTML qw( list );
print list( data => \@data, col => 2 );
print Spreadsheet::HTML::select( data => \@data, row => 0 );

Note that select() is not exportable, due to the existance of Perl's built-in select() function.

METHODS

• list( ordered, col, row, %params )

  Renders ordered <ol> and unordered <ul> lists.

LITERAL PARAMETERS

• headless

  Boolean. Discard first element. Useful for datasets that include headings.

  headless => 1

• ordered

  Boolean. Uses <ol> instead of <ul> container when true.

  ordered => 1

• col

  Integer. Start at this column. If neither col nor row is specified, then the first column (0) is used.

  col => 2

• row

  Integer. Start at this row. If neither row nor col is specified, then the first column (0) is used (not the first row).

  row => 0

TAG PARAMETERS

• ol

  Hash reference of attributes.

  ol => { class => 'list' }

• ul

  Hash reference of attributes.

  ul => { class => 'list' }

• li

  Accepts hash reference, sub reference, or array ref containing either or both.

  li => { class => [qw( odd even )] }
  li => sub { ucfirst shift }
  li => [ { class => 'item' }, sub { sprintf '%2d', shift } ]

• select( col, row, values, selected, placeholder, optgroup, label, %params )

  Renders <select> lists.

LITERAL PARAMETERS

• headless

  Discard first element. Useful for datasets that include headings.

  headless => 1

• col

  Integer. Start at this column. If neither col nor row is specified, then the first column (0) is used.

  col => 2

• row

  Integer. Start at this row. If neither row nor col is specified, then the first column (0) is used (not the first row).

  row => 0

• values

  Optional boolean. Default false. The selected row or col will be used as the <option> tags' CDATA value.

  values => 0

  When set to true the selected col or row will be used as the <option> tags' 'value' attribute and the NEXT col or row (respectively) will be used as the <option> tags' CDATA value.

  values => 1

• selected

  Optional scalar or array ref of default <option> CDATA values (if values is false>) or <option> 'value' attributes (if values is true) to be initially selected.

  selected => 'id1'
  selected => [qw( id1 id4 )]

• placeholder

  Optional string. Inserts the placeholder as the first <option> in the <select> list. This <option> will always have a value attribute set to empty string regardless of the value of values.

  placeholder => 'Please select an option'

• label

  Emits <label> tag for list. Either a scalar string or a special hash ref whose only key is the CDATA for the <label> and the only value is the attributes as a hash ref.

  label => 'Label with no attributes'
  label => { 'Label with attributes' => { class => 'label' } }

• optgroup

  Optional array ref of scalars.

  optgroup => [ 'Group 1:', 'Group 2:', 'Group 3:' ]

TAG PARAMETERS

• select

  Hash reference of attributes.

  select => { class => 'select' }

• option

  Accepts hash reference, sub reference, or array ref containing either or both.

  option => { class => [qw( odd even )] }
  option => sub { uc shift }
  option => [ sub { uc shift }, { class => [qw( odd even )] } ]
