Is the class test applied to the dropdown (check this in code view)? Is the style css file included on your page? Do you see the entry in the style css file?
After adding line bellow styles started to work and I see options to edit style in Design tab. <link rel="stylesheet" href="/css/style.css" /> @Teodor I believe this is a bug and you can easily reproduce this on a newly created project.
Hello Notum,
the same thing occured on my project right now. This surely looks like a bug.
After reading other posts about this, I think it only happens with node.js.
Cheers, Jo
