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