[franknoirot]

There is a component at src/components_old/applyform.js for reference.

Be aware of the trickiness of uploading documents to Dato, maybe there is a faster and cleaner way to accomplish this. Also try to add in validation for file size of images as well while working on this.

This is a basic NextJS blog post on forms for reference.
