Surface - Set custom CSS error class for text inputs
Hello!
I am stuck figuring out how to set a custom CSS classes for text inputs in Surface. Basically, I would like to add a red border for the invalid text field. I can probably use class={invalid: @field_status}, but I am wondering if there is somehow a way to make this apply for all fields by creating some kind of helper or wrapper. For the reference, I am using Ecto and there are changesets involved for the forms in question.
Any help, pointers, links are much appreciated. Thank you!

Thank you for the answer @Malian!
As you suggested, I could probably get away with a derived input component. What I had in mind was a tighter coupling to Ecto changesets, but that coupling might be too tight. On the other hand all the information is already probably there.
The idea sparked after reading Dynamic forms with Phoenix « Plataformatec Blog post and especially the “Customizing Inputs” section. I am thinking if Surface has an Field tag that acts as a wrapper for inputs and error tags it might be quite easy to add an error CSS class to the inputs that the field is wrapping. With that said, I haven’t looked at the Surface’s code too close yet so take my thoughts with a pinch of salt.
What do you think? Is it doable or is it not in line with Surface’s design philosophy?
