RTL Support

RTL Support Overview

RTL Support is a building block you will reach for often in design systems. It keeps related logic together and makes your intent obvious to reviewers and future maintainers.

When you learn rtl support properly, you avoid the guesswork that leads to bugs and rework. The example below shows the shape you will use in most real design systems projects.

<button
  type="button"
  aria-expanded="false"
  aria-controls="menu"
>
  Options
</button>
<ul id="menu" role="menu" hidden>
  <li role="menuitem" tabindex="-1">Edit</li>
</ul>

Accessible components pair correct roles and ARIA state with full keyboard support.

RTL Support Example

/* Tokens flow into components, which flow into products */
:root { --color-brand-500: #2563eb; }
.button { background: var(--color-brand-500); }

• Start from a minimal RTL Support example and grow it only as needed.
• Keep configuration explicit so RTL Support behaves the same in every environment.
• Name things clearly so teammates understand your RTL Support at a glance.
• Add tests around RTL Support early to lock in expected behaviour.

How RTL Support Fits into a Design System

RTL Support connects the design decisions in your system to the code teams actually ship. When it is defined once and reused, products stay consistent and updates roll out everywhere.

Accessible components pair correct roles and ARIA state with full keyboard support.

• Define it once as a token or shared component.
• Document intended usage with clear examples.
• Make it themeable and accessible by default.
• Version and release changes so consumers can upgrade safely.

Getting Teams to Adopt RTL Support

Adoption is where design systems succeed or stall. Make rtl support the easiest option: great docs, sensible defaults, and clear migration paths beat mandates every time.

Common Mistakes

• Skipping error handling and edge cases when wiring up rtl support.
• Leaving rtl support untested, so regressions slip into production.
• Over-engineering rtl support before you actually need the extra flexibility.
• Ignoring documentation, which makes rtl support hard for the next developer to change.

Key Takeaways

• RTL Support is a core part of working effectively with design systems.
• Start small and keep rtl support focused on a single responsibility.
• Apply consistent patterns so rtl support scales across your project.
• Test and document rtl support to keep it maintainable over time.
