Typo3 9.5.8 - accordion not rendering - Fluid layout?
I've been upgrading an older Typo3 project all the way from 6.2 up to 9.5 whilst also trying to keep the extensions compatible. One of them is df_contentslide
for rendering accordions, which had been working fine so far. With 9.5 I upgraded it to the latest version (7.0.0), but the functionality broke and instead of accordions only the raw text is being rendered. I ensured that the template was included. After some research I found this doc telling me that I had to
overwrite the FluidStyledContent-Layout
Comparing pre- and post-upgrade HTML code of the project, it actually became obvious to me that the layouts were different.
Now I'm not actually experienced with Typo3 or Fluid specifically, and I'm not quite sure what to make of said instruction. Do I have to register the given layout somewhere in the backend? Do I have to create a new template file with it? If so, why didn't it come with the extension? Or do I even have to tamper with the Fluid system files?
Any help would be greatly appreciated.
