📝 Walkthrough

Walkthrough

A component enhancement that adds horizontal scroll controls to tabs in DataViews. The implementation introduces scroll state tracking via refs and state, integrates ResizeObserver for dynamic scroll capability detection, and adds conditional arrow button UI for navigation without altering existing logic.

Summary

Tab Horizontal Scrolling Enhancement src/components/wordpress/dataviews.tsx

Added ChevronLeft and ChevronRight imports. Tightened TypeScript typing for window.wp.hooks declarations. Introduced tab scroll state management (tabsScrollRef, canScrollTabsLeft, canScrollTabsRight) with callbacks for scroll updates (updateTabsScrollState) and arrow-triggered scrolling (scrollTabsByArrow). Implemented scroll event listener and ResizeObserver integration within an effect hook to dynamically track scrollability and handle cleanup. Replaced static header with conditional left/right arrow Button UI wrapping the tabs container. Applied JSX and conditional formatting improvements throughout without functional changes.

ResizeObserver keeps it clear! ✨

In `@src/components/wordpress/dataviews.tsx`:
- Around line 907-971: The left/right arrow Buttons should not be conditionally
unmounted (which causes focus loss); always render both Button elements next to
the tabs container and toggle their disabled state based on
canScrollTabsLeft/canScrollTabsRight and make onClick a no-op when disabled (use
scrollTabsByArrow('left'|'right') only when enabled). Update the Button render
around tabsScrollRef so both Buttons are present, use the btn props
variant/size/className and wrap className values with cn(...) (as required by
src/components/**/*.{ts,tsx}) to merge Tailwind classes, and keep existing
aria-labels and Chevron icons unchanged so keyboard users retain focus while
arrows are visually/operationally unavailable.
- Around line 97-100: Guard against null before calling Object.keys on
v.filters: change the condition that sets the local variable filters (currently
using typeof v.filters === 'object') to also verify v.filters is not null (e.g.,
v.filters != null) and that it has keys (Object.keys(v.filters).length > 0);
update the assignment for filters (the variable named filters derived from
v.filters) to only JSON.stringify when v.filters is non-null and an object with
keys, otherwise set filters to null.
