string (field name)
Field name, which contains the thumbnail image used to represent the record visually whenever it is shown in FormEngine as a foreign reference selectable from a selector box.
This field must be a File abstraction layer field where icon files are selected. Since only the first icon file will be used, the Properties option should be used to allow only selecting a single icon file.
You should consider this a feature where you can attach an "icon" to a record which is typically selected as a reference in other records, for example a "category". In such a case this field points out the icon image which will then be shown. This feature can thus enrich the visual experience of selecting the relation in other forms.

tx_styleguide_elements_select_single_12_foreign is defined as
[ 'ctrl' => [ 'title' => 'Form engine elements - select foreign single_12', 'label' => 'fal_1', 'selicon_field' => 'fal_1', // ... ], 'columns' => [ // ... 'fal_1' => [ 'label' => 'fal_1 selicon_field', 'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig( 'fal_1', [ 'maxitems' => 1, ], $GLOBALS['TYPO3_CONF_VARS']['SYS']['mediafile_ext'] ), ], ], // ... ];
It can be used in another table as a foreign relation, for example in a field
with render type
