Add-on pricing selector

Lets buyers add support, storage, and compliance options while keeping the base plan and total visible. Checkbox changes recalculate the total and summarize selected additions in a polite status region. Optional costs remain itemized instead of being merged into an opaque custom quote.

Implementation field notes

Use add-on pricing selector 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

  • Pricing pages
  • Upgrade flows
  • Sales enablement

This pricing selectors 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.
