Implementation field notes

Use neon split action button 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

  • Deploy controls
  • Export modes
  • Create actions

This split actions pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The default action and disclosure are separate native buttons.
  • Alternate actions use menu roles and arrow-key navigation.
  • Escape closes the menu and restores focus to the disclosure.

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.
