Description

This PR resolves #1400 by implementing the missing FormHelperText component wrapper from @mui/material into the Sistent design system base components directory matrix.

Changes Proposed

  • Created FormHelperText directory component under src/base.
  • Implemented SistentFormHelperTextProps extending MUI's core typings to preserve strict type definitions.
  • Exported the component locally and globally via the root module index.
  • Verified successful production builds locally using cross-env and tsup.

cc @leecalcote @KhushamBansal
Please review this PR and let me know if any changes are required. Happy to iterate!

Summary by CodeRabbit

  • New Features
    • Form helper text is now available through the base component exports and can render using a custom element, such as a span.
    • Supports custom class names, error-state styling, and ref forwarding.
  • Improvements
    • Custom root elements can be used while retaining support for their properties.
  • Tests
    • Added coverage for child rendering, custom elements, class names, error states, and ref forwarding.

Code Review

This pull request introduces a new wrapper component, FormHelperText, which wraps Material-UI's FormHelperText component, and updates peer dependency flags in package-lock.json. The review feedback recommends wrapping the new component with React.forwardRef to ensure proper integration with other components and form libraries by forwarding the ref to the underlying DOM element.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Hi @KhushamBansal, thank you for the review! I have addressed the bot's feedback by wrapping the component in React.forwardRef and adding the displayName. I've also amended the commit to include the DCO sign-off. Please let me know if it looks good to go!

@KhushamBansal That makes total sense, it is indeed a text wrapper and not an icon. I had renamed it earlier based on the previous review request, but I have now reverted the file name back to FormHelperText.tsx and fixed the exports. @Bhumikagarggg FYI! The DCO check is passing. Let me know if it looks good to merge now.

Walkthrough

The PR adds a FormHelperText wrapper around MUI’s component, tests its rendering and ref behavior, and exports it through the local and base barrels.

Changes: FormHelperText component

Layer / File(s) Summary
Wrapper behavior and public exports
src/base/FormHelperText/FormHelperText.tsx, src/base/FormHelperText/FormHelperText.test.tsx, src/base/FormHelperText/index.ts, src/base/index.tsx
The wrapper forwards props, children, and refs to MUI’s component. It exports a generic props alias and sets a display name. Tests cover children, refs, custom elements, class names, and the error class. Both barrels export the component.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: Moderate · up to 75b06

The previously reported lint failure should be checked with the locked dependencies before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 66b92

The new public component delegates rendering to the existing MUI component. No security boundary change is visible, although its use by applications is not shown.

Retained concerns
No architecture-level concerns identified.

@KhushamBansal, since FormHelperText is a pure structural base wrapper around Material-UI’s core component with forwarded ref and type definitions (rather than an interactive or visual feature widget like a table/modal), it is primarily designed to be consumed downstream within form controls (e.g., FormControl, TextField).

The component has been verified with local tsup production builds and strict TypeScript lint checks (all CI checks are passing green). I've resolved the empty interface ESLint warning as well. Let me know if there are any other specific code-level checks needed, or if it looks good to merge!

Hi @PARTH-TUSSLE @Bhumikagarggg @KhushamBansal @chellej,
I have pushed the updates addressing the feedback:

Preserved polymorphic typing using MUI's OverridableComponent and generic SistentFormHelperTextProps, ensuring full flexibility for props like component="span".

Added a unit test in FormHelperText.test.tsx asserting that component="span" correctly renders a element.

Ran a formatting pass on FormHelperText.test.tsx matching repository conventions.
All checks and DCO sign-off are green. Ready for your review and approval!

Hey @abhinavkdeval08-design , Looks good overall. One thing I'd like you to check before merging:
The component supports polymorphic rendering through the component prop, but forwardRef currently fixes the ref type to HTMLParagraphElement.

For example, when using component="span", the underlying element is a span, while the implementation still types the forwarded ref as a paragraph element. The final as FormHelperTextComponent cast can hide this mismatch.

Could you align the ref typing with the polymorphic OverridableComponent API (following the pattern used by similar Sistent/MUI wrappers) and, if possible, cover the custom-component ref case as well?

Hi @PARTH-TUSSLE,

Updated in commit 9bbb4e0! Refactored the forwarded ref type to HTMLElement instead of narrowing to HTMLParagraphElement or using any. This maintains strict type safety (satisfying @typescript-eslint/no-explicit-any) while preserving the polymorphic OverridableComponent contract across custom root elements like component="span".

The custom-component ref unit test is in place and all DCO/linter checks are green. Looking forward to your re-review and approval!

Hi @PARTH-TUSSLE @Maanvi212006 @KhushamBansal,

Following up on the polymorphic ref implementation from commit 9bbb4e0:

  • Refactored forwarded ref type to HTMLElement to satisfy @typescript-eslint/no-explicit-any while preserving the OverridableComponent polymorphic contract for custom root elements (component="span").
  • Regression unit test asserting component="span" resolving to HTMLSpanElement is passing.
  • Branch is rebased cleanly on latest master with zero conflicts and DCO verified.

Since the technical requirements from the previous review are fully met, could you please re-review to clear the current "Changes requested" review block and trigger the awaiting workflows so this is unblocked for merge? Thank you!

# Project agent memory

## Repo state that looks broken but is pre-existing

A type contract can still be gated, just not by a type-only assertion file: jest transforms with
`@swc/jest`, which strips types without checking them, so such a file passes no matter what it
asserts. Shell out to `tsc` over a scoped fixture, assert the fixture is in the compiled program
(`--listFiles`) before trusting an empty diagnostic list, then filter the diagnostics to that
fixture. [`src/__testing__/helpers/tscFixture.ts`](src/__testing__/helpers/tscFixture.ts) is that
harness, and documents each check that keeps the filter from turning the guard vacuous - call
`typeCheckFixture(fixture, project)` from a new guard rather than copying it, because a fix to one
copy silently leaves the other unguarded. `navigationItemTitleTypes.test.ts` and
`schemaConstructAliasTypes.test.ts` are the two worked callers; both assert "compiles the fixture"
before the emptiness assertions, and the ordering is load-bearing.

Thank you so much @suttonskate! I'll definitely add this to the upcoming Meshery Dev Meeting agenda.

In the meantime, just a quick note that all review feedback from @PARTH-TUSSLE and @KhushamBansal (polymorphic OverridableComponent / HTMLElement ref typing in 9bbb4e0, component="span" unit test coverage, demo video, and DCO sign-off) has already been addressed on the current head (75b06ad).

@suttonskate @PARTH-TUSSLE — whenever you have a second, could you please clear the stale "Changes requested" status and trigger the pending CI workflows so this is ready to merge? Thank you!

Thanks for the nudge. One correction: I never requested changes on this PR, so there is no stale Changes requested status from me to clear. The blocking requests are Bhumikagarggg's from July 5 and PARTH-TUSSLE's from August 30 and September 1, and only they can clear theirs by re-reviewing. PARTH-TUSSLE's last note (September 27) was about the polymorphic ref typing, and the HTMLElement ref type from 9bbb4e0 is on the current head, so that one is his to confirm. On CI: only triage and DCO ran here and both are green, with no workflow pending, and my token cannot trigger workflows. Happy to review if you add me as a reviewer.

Thank you @suttonskate! Since I don't have triage permissions on the repo yet, the Reviewers picker doesn't let me add new reviewers—if you're able to add yourself on the sidebar, I'd really appreciate your review!

@Bhumikagarggg @PARTH-TUSSLE — also requested a re-review from both of you to clear the earlier blocks:

  • @Bhumikagarggg: Filename (FormHelperText.tsx) and package-lock.json were reverted back in 483690c / f760be4.
  • @PARTH-TUSSLE: Polymorphic HTMLElement ref typing (9bbb4e0) and the component="span" unit test (66b92bd) are in place on the current head.

Thanks for following up, and for the clear summary of what changed since the earlier reviews. I checked the current head (75b06ad) and the change looks good.

Verified on this head:

  • Filename is back to FormHelperText.tsx (483690c), and package-lock.json is untouched by this PR.
  • The polymorphic ref typing PARTH-TUSSLE asked about is in place: forwardRef takes React.Ref (9bbb4e0), with the component="span" render and ref tests in place (66b92bd, 27807a7).
  • The wrapper matches the sibling pattern (FormControl is the same thin pass-through shape), and the tests cover render, ref forwarding for both the default paragraph and a span, plus className and the error state.
  • Triage and DCO are green; no other checks run on this PR.

One optional nit, not blocking: the export * from ./FormHelperText line sits at the end of src/base/index.tsx rather than in alphabetical order with the other exports. Feel free to move it, or leave it.

Note for the merge: my approval does not clear the earlier change requests. Bhumikagarggg and PARTH-TUSSLE still need to re-review to clear theirs, as you already asked them to.

Thank you so much for the thorough review and approval @suttonskate! I'll leave the barrel export order as-is so we don't reset your approval.

One quick heads-up: it looks like @Bhumikagarggg hasn't been active in the community since July, so once @PARTH-TUSSLE confirms the polymorphic ref typing on his end, a maintainer may need to dismiss @Bhumikagarggg 's stale review so this can merge. Thanks again!
