In modified 1.x shops, the module creates a new category in the Content Manager "FAQ" and displays the entries from this category in the shop in a FAQ module with a sliding effect, so that the questions are displayed below each other and the corresponding answer slides open when you click on a question.
You can store the link to the FAQ page somewhere in the template or in the text.
In Modified 2.x shops there is an extra menu item "FAQ Manager" where questions and answers are stored. The FAQ item is then integrated as normal in a Content Manager entry, the whole thing also bilingual German/English.
If you click on a question, the answer slides to the bottom.
Of course, this includes adaptation to your shop colours. Slight adjustments are also necessary for Modified 2 shops, so they are not 100% "update-proof".
