Put the Field Label of a Custom Element in a Transaction HTML Layout

It is currently not possible to automatically add the Field Name of a Custom Element that is added in a Custom Transaction HTML Layout. The user has to add it manually to the layout.

1. Navigate to Customization > Forms > Transaction Form HTML Layouts.
2. Edit the Custom HTML form that is used.
3. In the Templates tab > Body section, add <b>Field Name</b><br> next to the custom element added.
