One issue I have encountered: because all the components are in one common @layer, placing FileUpload inside a Field causes .ds-field to overwrite styles on .ds-file-upload (being a label) due to usage of stronger selectors (:is()). For now I have solved this by repeating the class twice .ds-file-upload.ds-file-upload {} to get same specificity (0.2.0) and then it wins by being later in the css order.

Tested with VoiceOver.

Label in field gives weird behavior. Image is showing reading order of elements.

Image from screen reader:

Text inside works fine:

We need to discuss:

• Should we support label outside of dropzone? If so, how do we create a robust screen reader experience?
• We need to think about the "slipp filer her" text. This is something we might want to hide from screen readers. How do we support this and flexible texts 🤔

Someone else will need to take over this branch and write the documentation. The component is ready but needs code-review for the latest changes.
This pr installs react-dropzone as a devDependency in the react package which is not ideal. But it is useful to have a functional test of this in storybook since downstream users will use it, and it affects the component 🤷

9. juni 2026, Status fra @oddvernes @eirikbacker @mimarz :
   Det er kun docs som gjenstår. Viktig å få med i dokumentasjonen hvor en skal sette props fra react-dropzone sånn at alt blir lest av skjermleser.

Note to self: Me and @eirikbacker want to try and see if we can reduce the number of sub-components to promote composition of existing components.

Not only that, but I can bet you people will use <Input> inside <Fileupload> (instead of <Fileupload.Input>), and we should see if we can make that work.
