List

Class: Code16\Sharp\Show\Fields\SharpShowListField

This field is very similar to the Form's File field, and its purpose is to display items made of other Show fields.

Here's an example, for a list of pictures with a legend:

class MyShow extend SharpShow
{
    // [...]
    function buildShowLayout(ShowLayout $showLayout): void
    {
        $showLayout->addField(
            SharpShowListField::make('pictures')
                ->setLabel('additional pictures')
                ->addItemField(
                    SharpShowFileField::make('file')
                        ->setStorageDisk('local')
                        ->setStorageBasePath('data/Product/{id}/pictures')
                )
                ->addItemField(
                    SharpShowTextField::make('legend')
                        ->setLabel('Legend')
                )
        );
    }
}

Configuration

setLabel

Set the field label.

addItemField

Add a SharpShowField in the item.

Layout

The List item layout must be defined like the show itself, in the buildShowLayout() function. The item layout is managed as a column, with a ShowLayoutColumn object. To link the column and the item, use the classic withField() function with a second argument, a Closure accepting a ShowLayoutColumn.

Example:

class MyShow extend SharpShow
{
    // [...]
    function buildShowLayout(ShowLayout $showLayout): void
    {
        $showLayout->addColumn(6, function (ShowLayoutColumn $column) {
             $column->withListField('pieces', function (ShowLayoutColumn $listItem) {
                  $listItem->withField('acquisition_date')
                      ->withField('title')
                      ->withField('artist');
             });
         });
    }
}

Formatter

The Formatter expects an array or a Collection of models, each one defining attributes for each list item keys at the format expected by the corresponding Field Formatter.
