Import data dropzone

Explains CSV requirements, accepts a file, and previews mapping readiness before any import starts. Drop and keyboard file selection share one native input while status reports the chosen file. Format guidance and preflight state appear beside the upload target instead of after rejection.

Implementation field notes

Use import data dropzone confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Product activation
  • Data migration
  • Workspace setup

This import workflows pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • Interactive targets use labelled native controls and retain a visible focus treatment.
  • State, totals, filtering, and errors are communicated with persistent text instead of color alone.
  • The layout reflows without changing the semantic reading order, and motion respects reduced-motion preferences.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt primary accent, secondary accent, surface color, text color through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
