Fixes #8626

This PR adds responsive split-view behavior in Data Views (and the Query Builder).

  • Measures the available content area instead of the full browser window.
  • Automatically switches from horizontal to vertical when both panes cannot fit.
  • Preserves enough room for the form pane when dragging the divider.
  • Keeps split view available on narrow layouts (splits horizontally instead of vertically).

Testing instructions

Open any Data View with split view enabled (it is by default, and also test split view in the Query Builder). Test against main to make sure the new behavior is more desirable.

  • On a wide window, verify that the vertical split is the default.
  • Make sure you can switch to horizontal split.
  • Drag the divider toward the form pane.
  • Verify the divider stops before the form pane becomes too narrow and that the complete form remains accessible.
  • Narrow the window or zoom in a bunch.
  • Verify the layout automatically switches to a vertical split.
  • Widen the available content area again.
  • Verify the preferred horizontal orientation is restored.
  • Open the Data View query editor, modify the query, and save it and make sure it displays properly.
  • Repeat the resize, drag-limit, and orientation checks in Query Builder split view.

Summary by CodeRabbit

  • New Features

    • Split views now respond to the available container space rather than the overall screen width. Horizontal splitting is available when there’s room for both panes, and pane width adjusts to fit.
    • Your selected split orientation is retained when space allows.
  • Bug Fixes

    • Changing split orientation now resets pane sizing to prevent stale layouts.

📝 Walkthrough

Walkthrough

The split view now responds to its container width instead of a fixed window-width threshold. Data Views and Query Builder use the available width to determine horizontal split availability and the primary-pane maximum width.

Changes

Responsive split view

Layer / File(s) Summary
Container width tracking and thresholds
specifyweb/frontend/js_src/lib/hooks/useResponsiveSplitView.ts, specifyweb/frontend/js_src/lib/components/DataViews/__tests__/useResponsiveSplitView.test.tsx
The new hook observes container width and reports whether horizontal splitting is available, the orientation, and a maximum primary-pane width. Tests cover the minimum width, preferred vertical orientation, and replacement containers.
Data Views integration
specifyweb/frontend/js_src/lib/components/DataViews/index.tsx
Data Views uses the responsive hook instead of a window-width split gate. It passes the computed width limit to the split view and disables the orientation control when horizontal splitting is unavailable or split view is off.
Query Builder responsive state and controls
specifyweb/frontend/js_src/lib/components/QueryBuilder/useQuerySplitView.ts, specifyweb/frontend/js_src/lib/components/QueryBuilder/Header.tsx, specifyweb/frontend/js_src/lib/components/QueryBuilder/Wrapped.tsx
The Query Builder hook returns responsive split availability, a container ref, and a maximum primary-pane width. The header and builder wiring use these values.
Query Builder container and pane sizing
specifyweb/frontend/js_src/lib/components/QueryBuilder/QueryBuilderResults.tsx, specifyweb/frontend/js_src/lib/components/QueryBuilder/ResultsWrapper.tsx, specifyweb/frontend/js_src/lib/components/QueryBuilder/SplitView.tsx, specifyweb/frontend/js_src/lib/components/QueryBuilder/__tests__/SplitView.test.tsx
The results components pass the container ref and width limit to SplitView. The primary pane uses the supplied limit, and its saved state is cleared when orientation changes. A test checks that reset.

Container-only resizing lacks direct test coverage, but no corresponding production failure was established. The change is mergeable with this bounded test follow-up.

Exercise the ResizeObserver callback in this test.

useResponsiveSplitView updates its width through both the ResizeObserver callback and the window resize listener. This test dispatches only the window event. Because the shared mock does not retain or invoke the observer callback, a regression in container-only notifications can pass. Make the mock callback-capable and invoke the callback after changing clientWidth.

Testing instructions

Open any Data View with split view enabled (it is by default, and also test split view in the Query Builder). Test against main to make sure the new behavior is more desirable.

  • On a wide window, verify that the vertical split is the default.
  • Make sure you can switch to horizontal split.
  • Drag the divider toward the form pane.
  • Verify the divider stops before the form pane becomes too narrow and that the complete form remains accessible.
  • Narrow the window or zoom in a bunch.
  • Verify the layout automatically switches to a vertical split.
  • Widen the available content area again.
  • Verify the preferred horizontal orientation is restored.
  • Open the Data View query editor, modify the query, and save it and make sure it displays properly.
  • Repeat the resize, drag-limit, and orientation checks in Query Builder split view.

Looks good to me! This worked for both data view and queries in the pri and naturkundemuseum databases.

Looks great! Only thing I noticed that might be more of a nitpick than a concern is when you zoom in or zoom out that you have to manually adjust for void space of the record, you could possibly make it to expand the size of the record being shown on dual display

This is the page 50% zoom out

Other than that it works great
