# Bug Report

## Prerequisites

* [ ] Can you reproduce the problem on TYPO3 v11.5 LTS
* [x] Can you reproduce the problem on TYPO3 v12.4 LTS
* [x] Did you [perform a cursory search](https://github.com/issues?q=is%3Aissue+user%3Abenjaminkott+repo%3Abenjaminkott%2Fbootstrap_package)
to see if your bug or enhancement is already reported?

## Description
Only tiny issue: Form template in EXT:form\Resources\Private\Frontend\Templates\Form.html has the line
`additionalAttributes="{formvh:translateElementProperty(element: form, property: 'fluidAdditionalAttributes')}"`
Your template in Resources\Private\Templates\Form\Form.html not.

Compare EXT:form\Resources\Private\Frontend\Templates\Form.html with Resources\Private\Templates\Form\Form.html, focusing on the formvh:translateElement expression for fluidAdditionalAttributes. Update the package template so it includes the same additionalAttributes attribute, then verify the target template matches the reference.
