Description

This PR fixes #8007.

Note

Stacked PR Notice:
This branch is stacked on top of PR #8021 (addressing #8008). Once PR #8021 is merged into master, this PR will cleanly isolate the 4 commits specific to #8007.

In /cloud-native-management/meshery/getting-started, clicking on the sidebar indicator items (Install, Patterns, Performance) did not navigate to their corresponding sections.

Solution

  1. Target Step Anchors & Responsive Offset:
    • Generated and bound deterministic IDs to <StepWrapper> components.
    • Added responsive scroll-margin-top offsets (9.5rem desktop, 6rem mobile/tablet) so clicked sections align cleanly below the sticky navbar and level with the sticky terminal.
  2. Smooth Scroll Navigation:
    • Implemented handleStepClick in AnimatedStepsList using element.scrollIntoView with fallback for prefers-reduced-motion.
    • Updated AnimatedStepsList.style.js to preserve sticky positioning for nav landmarks.
  3. Typography & Theme Scheme Integration:
    • Converted indicator items to semantic <a> anchor links with aria-current="step", eliminating button user-agent backgrounds and global button box-shadows.
    • Applied Layer5 theme tokens (props.theme.greyB4B4B4ToGrey505050 for inactive contrast, props.theme.secondaryColor for clean brand hover, and props.theme.text for active states).

📝 Walkthrough

Walkthrough

The animated steps list now renders indicator anchors, forwards stable step IDs, handles smooth or reduced-motion scrolling, updates the active indicator and fragment URL, and applies navigation-specific responsive styling.

Changes

Animated steps navigation and layout

Layer / File(s) Summary
Indicator link structure and states
src/components/Animated-steps-list/Steps-indicator/*
StepsIndicator now renders a nav structure with styled anchor links and invokes onItemClick before conditionally preventing default navigation.
Step anchors and scroll handling
src/components/Animated-steps-list/index.js, src/components/Animated-steps-list/Steps-list/*
Steps receive stable IDs. Indicator clicks resolve the target, scroll with reduced-motion support, update the active index, focus the heading, and update the fragment URL. Hash changes trigger the same synchronization.
Responsive indicator and step layout
src/components/Animated-steps-list/AnimatedStepsList.style.js, src/components/Animated-steps-list/Steps-list/Step/Step.style.js
Sticky indicator styling now applies to nav elements. Step sections receive responsive scroll margins and focusable headings without visible outlines.

Priority: ➖ Normal — Impact reflects medium issue severity.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to 56940

Sidebar links now support section navigation and URL fragments, but keyboard users may not see the focused destination and Back navigation can leave an incorrect sidebar item marked current. The remaining layout-token concerns are bounded styling maintainability risks.

Small improvement to make navigation behave like native fragment links:

Update the URL fragment after the programmatic scroll so deep-linking and the browser back button work. After your smooth scroll, call history.pushState(null, '', #${id}) (or replaceState if you prefer no history entry).

For accessibility, give the target heading tabindex="-1" and call .focus() on it after scrolling so screen readers announce the new context.

Thanks for the thoughtful review and recommendations, @dhruveshmishra!

Both improvements have been implemented:

  1. URL Fragment & History Synchronization:
    • Programmatic smooth scrolling now calls window.history.pushState(null, "", #${stepId}).
    • Added popstate and hashchange listeners in useEffect so that browser Back / Forward buttons and direct deep-linking (e.g., sharing a URL with #patterns or #performance) smoothly scroll to and activate the corresponding step.
  2. Accessibility (a11y):
    • Added tabIndex="-1" to each step's <h3> heading.
    • Called .focus({ preventScroll: true }) on the heading after scrolling so screen readers announce the new section context without interrupting the smooth scroll.

Here is a quick screen recording demonstrating the updated URL synchronization and smooth navigation:

Use theme values for the scroll offsets.

StepWrapper is a styled-component, but the new 9.5rem and 6rem values are hardcoded. Define these navigation offsets in the theme or an existing layout token and reference them here.

Hi @dhruveshmishra,

The issue with the section headings overflowing under the header in the Y-direction when navigating backwards has been resolved. The heading now correctly maintains proper clearance below the sticky navbar across both sidebar indicator clicks and browser back navigation.

Here is the video demonstration of the fix in action:

Screen.Recording.2026-09-08.at.2.44.04.PM.mov

All CodeRabbit review comments and ESLint checks have also been addressed. The PR is ready for your review!
