React Tabs / Multi-View Switcher

By FrontendAtlas Team · Updated Jan 30, 2026

Implement React tabs with a single activeTab state. Buttons update the value and conditional rendering shows only the active panel, with clear active styles and accessible button semantics. Include keyboard navigation and focus management for accessibility; test edge cases like repeated clicks and long labels.…

Render a tabbed UI with three tabs labeled "Overview", "Details", and "Settings".
Track which tab is currently active and visually highlight it.

What you’ll build / What this tests

This premium react coding focuses on React Tabs / Multi-View Switcher. You’ll apply react and state thinking with easy level constraints. The prompt emphasizes Implement React tabs with a single activeTab state. Buttons update the value and conditional rendering shows….

Learning goals

Translate the prompt into a clear react API signature and return shape.
Apply react, state, conditional-rendering techniques to implement react tabs / multi-view switcher.
Handle easy edge cases without sacrificing readability.
Reason about time/space complexity and trade-offs in react.

Key decisions to discuss

Define the exact input/output contract before coding.
Prioritize predictable edge-case handling over micro-optimizations.

Evaluation rubric

Correctness: covers required behaviors and edge cases.
Clarity: readable structure and predictable control flow.
Complexity: avoids unnecessary work for large inputs.
API discipline: no mutation of inputs; returns expected shape.
Testability: solution is easy to unit test.

Constraints / Requirements

Render a tabbed UI with three tabs labeled "Overview", "Details", and "Settings".
Track which tab is currently active and visually highlight it.
Render only the active tab's content at a time.
The initial active tab should be "Overview".
Clicking a tab makes it the active tab.
Only the active tab's panel is visible at any time.
The active tab button has a distinct visual style (e.g. filled pill) compared to inactive ones.
Use React state (useState) to store the currently active tab.
Model the tab id as a union type like 'overview' | 'details' | 'settings' for clarity in TypeScript.
Use conditional rendering (e.g. isActive('overview') && (...)) to show/hide each panel.

Mini snippet (usage only)

// Example usage
const input = /* react tabs / multi-view switcher input */;
const result = solve(input);
console.log(result);

// Edge case check
const empty = input ?? null;
const fallback = solve(input);
console.log(fallback);

// Expected: describe output shape, not the implementation
// (no solution code in preview)

Common pitfalls

Mutating inputs instead of returning a new value.
Skipping edge cases like empty input, duplicates, or nulls.
Overlooking time complexity for large inputs.
