+> ### IDE auto-completion in templates
+>
+> The `Zend\Form\View\HelperTrait` trait can be used to provide auto-completion
+> for modern IDEs. It defines the aliases of the view helpers in a DocBlock as
+> `@method` tags.
+>
+> #### Usage
+>
+> In order to allow auto-completion in templates, `$this` variable should be
+> type-hinted via a DocBlock at the top of your template. It is recommended that
+> you always add the `Zend\View\Renderer\PhpRenderer` as the first type, so that
+> the IDE can auto-suggest the default view helpers from `zend-view`. Next,
+> chain the `HelperTrait` from `zend-form` with a pipe symbol (a.k.a. vertical
+> bar) `|`:
+> ```php
+> /**
+>  * @var Zend\View\Renderer\PhpRenderer|Zend\Form\View\HelperTrait $this
+>  */
+> ```
+>
+> You may chain as many `HelperTrait` traits as you like, depending on view
+> helpers from which Zend Framework component you are using and would like to
+> provide auto-completion for.

+ * Helper trait for auto-completion of code in modern IDEs.
+ *
+ * The trait provides convenience methods for view helpers,
+ * defined by the zend-form component. It is designed to be used
+ * for type-hinting $this variable inside zend-view templates via doc blocks.
+ *
+ * The base class is PhpRenderer, followed by the helper trait from
+ * the zend-form component. However, multiple helper traits from different
+ * Zend Framework components can be chained afterwards.
+ *
+ * @example @var \Zend\View\Renderer\PhpRenderer|\Zend\Form\View\HelperTrait $this
+ *
+ * @method string|Form form(FormInterface|null $form = null)
+ * @method string|FormButton formButton(ElementInterface|null $element = null, string|null $buttonContent = null)
+ * @method string|FormCaptcha formCaptcha(ElementInterface|null $element = null)
+ * @method string|Dumb formCaptchaDumb(ElementInterface|null $element = null)
+ * @method string|Figlet formCaptchaFiglet(ElementInterface|null $element = null)
+ * @method string|Image formCaptchaImage(ElementInterface|null $element = null)
+ * @method string|ReCaptcha formCaptchaRecaptcha(ElementInterface|null $element = null)
+ * @method string|FormCheckbox formCheckbox(ElementInterface|null $element = null)
+ * @method string|FormCollection formCollection(ElementInterface|null $element = null, bool $wrap = true)
+ * @method string|FormColor formColor(ElementInterface|null $element = null)
+ * @method string|FormDate formDate(ElementInterface|null $element = null)
+ * @method string|FormDateTime formDateTime(ElementInterface|null $element = null)
+ * @method string|FormDateTimeLocal formDateTimeLocal(ElementInterface|null $element = null)

+ * @method string|FormDateSelect formDateSelect(ElementInterface $element = null, $dateType = IntlDateFormatter::LONG, $locale = null)
+ * @method string|FormElement formElement(ElementInterface|null $element = null)
