# Extend the Comment Form
Let's assume we create a Blog-Package and have to add an optional phone field to the comment form.
**Add the new Property to the NodeType and Inspector Section**
_Vendor.Blog/Configuration/NodeTypes.Comment.yaml_
'WebExcess.Comments:Comment':
properties:
phone:
type: string
ui:
inlineEditable: false
label: 'Vendor.Blog:NodeTypes.Comment:properties.phone'
reloadIfChanged: true
inspector:
group: 'comment'
editorOptions:
maxlength: 50
**Create a custom Comment-Model which includes the new Property**
_Vendor.Blog/Classes/Vendor/Blog/Domain/Model/Comment.php_
phone;
}
/**
* @param string $phone
*/
public function setPhone($phone)
{
$this->phone = $phone;
}
}
**Replace the original Comment-Model with your version**
_Vendor.Blog/Classes/Vendor/Blog/Configuration/Objects.yaml_
WebExcess\Comments\Domain\Model\CommentInterface:
className: 'Vendor\Blog\Domain\Model\Comment'
**Point to your custom Templates**
_Vendor.Blog/Configuration/Views.yaml_
-
requestFilter: 'isPackage("WebExcess.Comments") && isController("Comments")'
options:
templatePathAndFilename: 'resource://Vendor.Blog/Private/Templates/Comments/Index.html'
partialRootPaths: ['resource://Vendor.Blog/Private/Partials/Comments']
**Copy the Base-Template and add your Form-Field**
_Vendor.Blog/Resources/Private/Templates/Comments/Index.html_
**Overwrite the TextField-Partial to inject your custom Translation-File**
_Vendor.Blog/Resources/Private/Partials/Comments/TextField.html_
**Add your field translation**
_Vendor.Blog/Resources/Private/Translations/en/NodeTypes/Comment.xlf_
Phone
**Result**
Now your Blog-Package is using [webexcess/comments](https://github.com/webexcess/WebExcess.Comments) for all Feedbacks and offers an optional Phone-Formfield which is only visible to the editors.
So customers can open another feedback-channel.
Without ~~breaking~~ forking the original Package itself.
