How do i add a drop shadow to Text-elements like on the standard wix editor?
Hey @Katharina_steirer! 
I’m guessing you’re referring to Wix Studio, right? At the moment, it’s not possible to add drop shadow to text natively, although you can use CSS if you know a little.
Alternatively, text mask has drop shadows that you can use.
There’s also an open feature request for this. Worth adding your vote - Studio Editor Request: Additional Text Design Options | Help Center | Wix.com
Thank you very much Noah!
