[Solved] Does anyone have this working? Before I go down a rabbit hole of trying to workout why my optional fields are always shown

Out of curiosity do your optional fields correctly have the "umbraco-forms-hidden" class attached to them?

looks like it https://cdn.discordapp.com/attachments/1239913278629613588/1239914745792958546/image.png?ex=6644a817&is=66435697&hm=ef17184c97fbd1a06838137bb6dcb8fd30e1585667c27b40340e9be3385f59ea&

And then just for sanities sake, That class is actually applying a display:none to those fields?

It is not... and looking at my non modal one its using the Umbraco CSS

Now that is strange, As the Umbraco forms default theme should have that declared in its style sheet. The obvious temporary solution is to re-add that rule back into a stylesheet, but as to the reason its not there now begs the question of why. I'd guess this is a fresh install of forms vs a forms theme thats been upgraded through versions?

Same form same settings but different render methods block with render macro RTE macro
