Chris@0:  * @file
Chris@0:  * Default theme implementation for a form element.
Chris@0:  *
Chris@0:  * Available variables:
Chris@0:  * - attributes: HTML attributes for the containing element.
Chris@0:  * - errors: (optional) Any errors for this form element, may not be set.
Chris@0:  * - prefix: (optional) The form element prefix, may not be set.
Chris@0:  * - suffix: (optional) The form element suffix, may not be set.
Chris@0:  * - required: The required marker, or empty if the associated form element is
Chris@0:  *   not required.
Chris@0:  * - type: The type of the element.
Chris@0:  * - name: The name of the element.
Chris@0:  * - label: A rendered label element.
Chris@0:  * - label_display: Label display setting. It can have these values:
Chris@0:  *   - before: The label is output before the element. This is the default.
Chris@0:  *     The label includes the #title and the required marker, if #required.
Chris@0:  *   - after: The label is output after the element. For example, this is used
Chris@0:  *     for radio and checkbox #type elements. If the #title is empty but the
Chris@0:  *     field is #required, the label will contain only the required marker.
Chris@0:  *   - invisible: Labels are critical for screen readers to enable them to
Chris@0:  *     properly navigate through forms but can be visually distracting. This
Chris@0:  *     property hides the label for everyone except screen readers.
Chris@0:  *   - attribute: Set the title attribute on the element to create a tooltip but
Chris@0:  *     output no label element. This is supported only for checkboxes and radios
Chris@0:  *     in \Drupal\Core\Render\Element\CompositeFormElementTrait::preRenderCompositeFormElement().
Chris@0:  *     It is used where a visual label is not needed, such as a table of
Chris@0:  *     checkboxes where the row and column provide the context. The tooltip will
Chris@0:  *     include the title and required marker.
Chris@0:  * - description: (optional) A list of description properties containing:
Chris@0:  *    - content: A description of the form element, may not be set.
Chris@0:  *    - attributes: (optional) A list of HTML attributes to apply to the
Chris@0:  *      description content wrapper. Will only be set when description is set.
Chris@0:  * - description_display: Description display setting. It can have these values:
Chris@0:  *   - before: The description is output before the element.
Chris@0:  *   - after: The description is output after the element. This is the default
Chris@0:  *     value.
Chris@0:  *   - invisible: The description is output after the element, hidden visually
Chris@0:  *     but available to screen readers.
Chris@0:  * - disabled: True if the element is disabled.
Chris@0:  * - title_display: Title display setting.
