Extension to replace formfildset?

Hi,

Back in the days, I could use the extension formfieldset to packing my formfields. But since Contao v 2.9.5 (I think) it suddenly dosen't work anymore. Just tried to update to v 2.10.4, but as I expected it still not working. So I think formfildset is bit outdated in Contao - but is there any other extensions there can replace formfieldset and do what I want it to do?

Please help me out here :roll:

Use one Html element before and on after your group of fields, and write <fielset> tags in it (<fieldset>to open and </fieldset> to close).
If you want to add a legend, use <legend>your text</legend> in the first html element after your <fieldset> tag.

If you are using a tableless form layout there are already the required form elements to do this.
