A list of updates and changes to Rails Blocks.

March 20th 2026

  • • Improved combobox and select: added openOnMouseDown and lockScroll options and improved dropdown scroll locking inside dialogs and overlays.
  • • Improved dropdown: Fixed the lockScroll option, which had an edge case issue with nested submenus.

New: Shared Partials, ViewComponents & Markdown documentation

Since the beginning of the year, I've been working on creating Shared Partials and ViewComponents for all 52 component sets that were released in 2025, and I'm glad to announce that they are finally ready! 🙌
I've also added Markdown documentation for each component set so you can easily ask questions about them in your LLM of choice, or give enough context before customizing Rails Blocks components.

I also updated dependencies:

  • • Tailwind CSS to v4.2.0
  • • Pagy to v43.3.1
  • • Floating UI to v1.7.6
  • • Tom Select to v2.5.2

February 2026

In February 2026, I also shipped these fixes and improvements:

  • • Fixed lightboxes opening behind dialog-based components (modal, drawer, and slideover)
  • • Improved shared modal and slideover overlays: synchronized scroll-lock and scrollbar compensation across nested overlays, and hardened div-based modal behavior when portaled to <body>
  • • Revamped the drawer interaction and animation system (smoother snap/drag/open motion), and improved the first-open of asynchronously loaded content UX across drawer, modal, and slideover by temporary disabling the button
  • • Updated toast stacking: toasts now stay above <dialog> elements
  • • Refactored the marquee animation engine for smoother slow-on-hover and resume behavior across Safari and Chrome
  • • Fixed a Safari blinking issue when closing the feedback widget after submit or manual close
  • • Added a new vertical marquee component
  • • Improved popover stacking behavior in sticky layouts
  • • Improved stepper: smoother entrance behavior, persistent current/visited step restoration, and submit loading state support
  • • Refactored two factor to use dynamic digit targets (instead of num1..num6) and added optional numericOnly mode
  • • Fixed tabs disabled-state behavior: disabled tabs are skipped during keyboard navigation and cannot be activated
  • • Updated collapsible with instant icon switching and a new animated option to disable content motion when needed
  • • Added a new plus/minus icon example for collapsible
  • • Improved the carousel controller behavior and added a new vertical carousel example
  • • Improved dropdown and context menu interactions: smoother nested submenu focus/highlight behavior during fast pointer movement
  • • Improved sidebar component examples with better styling for the profile when the sidebar is collapsed

  • Rails Blocks is a modern component library for Ruby on Rails applications. It provides production-ready UI components that integrate seamlessly with Hotwire, Stimulus, and Tailwind CSS.

    Built with Rails conventions in mind, each component works perfectly with Turbo Drive, Turbo Frames, and Turbo Streams. All components are fully responsive and support both light and dark modes out of the box.

    Build modern, interactive web applications without extensive JavaScript. The library leverages Stimulus controllers for interactivity while keeping your Rails application fast and native.

    Every component is copy-and-paste friendly, giving you full control. Customize styles, behavior, and markup to fit your needs while maintaining consistency across your application.
