Graph/overflow-expanded-placement

Pattern

Unbounded Expanded Placement

overflow-expanded-placement

A UI expansion anchor ignores viewport or container constraints, causing expanded content to overflow or behave inconsistently (e.g., assumed centering or single-expanded state). Fixes shift alignment and/or model explicit expansion state to prevent overflow and broken interactions.

The image gets outside its parent bounds. — wrapped in a shadcn Dialog. Tension: I tried using different combinations of object-contain, percentages (`h-[80%]`), and fractions (`h-3/4`) but I didn't manage to accomplish it. Outcome: I made it work with the suggestion from @rozsazoltan and using `!max-w-fit` in the DialogContainer.

The shadcn/Radix navigation menu centers its content around the trigger, so when the viewport content is wider than the browser window it overflows and can push outside the viewport. The user wants automatic detection of overflow and shifting the menu content to the right to avoid overflow.

the Table is still overflowing the ScrollArea instead of causing it to scroll — I have a ScrollArea component that's supposed to take the full width of its container and add a horizontal scroll bar when the content overflows. Tension: Inside this ScrollArea, I have a Table component that's overflowing its container.

expanding a parent row does not display the sub-rows — combine the virtualization example with the Expanding Sub-Rows Guide. Outcome: Could you please provide guidance on how to properly combine these two features?

In TanStack/MRT table grouping with expandable group rows, users that have only one associated Scope should not show as expandable/expandable groups. The table currently allows expansion even when a group has just one leaf row.

Scroll snap styling (snap-y/snap-mandatory on the parent and snap-start/snap-center on child cards) does not work when cards are placed in a vertically stacked flex layout under a sticky header. Scrolling occurs without snapping to the card boundaries.

A child element set with a fixed `aspect-ratio: 16/9` overflows the parent vertically when the parent's `max-height` is much smaller than the computed height from the parent's `max-width`. The child’s size won’t respect the height constraint even when using `w-full`/`h-full`/`max-*` classes.

it results in a very narrow and tall tooltip that wraps on every other word or it fails to wraps and exceeds the max width — Whenever I try to implement it in tailwind. Tension: I want the `div` with `absolut. Outcome: is there a way to do the same thing in tailwind?

A child inside a flex-grow container keeps expanding with its content, but one sub-site needs its content to be constrained to the parent's height and overflow-scroll instead. The parent container styles should not be modified.

In a flex row layout, an element with a fixed flex-basis of `800px` does not shrink when the viewport becomes smaller, while the other element shrinks. Using percentage basis values makes both elements shrink as expected.

Each size modifier comes with a baked in `max-width` designed to keep the content as readable as possible. — Overriding max-width. Tension: This isn't always what you want though, and sometimes you'll want the content to just fill the width of its container. Outcome: add `max-w-none` to your content to override the embedded max-width.

The navigation menu, shown via absolute positioning on small screens in a React + Tailwind header, is not perfectly centered when toggled. Attempts like using `left-[15%]` (or `right-[22%]`) do not produce consistent centering.

Hovering over one React card causes both cards to expand, despite intending independent hover behavior for each card.

The grid inside a container styled with flexbox is not centering as expected, so the rendered cards appear misaligned within their parent area.

After adding Tailwind classes `flex-grow min-h-screen` to the home page layout (with MUI/React), an unnecessary vertical scrollbar appears. This happens because the page becomes taller than the viewport.

In a Next.js app using Quill with quill-blot-formatter, image resizing works but alignment (left/right/center) does not change the image position when the toolbar icon is clicked.

strcpy(overflowing, overflowingtext) does not reliably overflow into p1

Buffer overflow cannot be demonstrated reliably

When the MUI Select dropdown is used inside an iframe, selecting any option causes the viewport to soft scroll to the top of the form.

In a React Native app, the UI content is rendered behind the device status bar, causing overlap even after using react-native-safe-area-context and SafeAreaView.

I expect the grid layout will occupy the area indicated by the line. — I am trying to create a React layout. Tension: the inner grid stretch I have tried below. But this also does not seem to work. Outcome: It is important to define the root parent as `Grid2` with a specified `size`.

it responding to `n+1` events later than it actually should — Because resize events often occur as many events in quick succession as the user drags their mouse to resize the window. Tension: the resize behaviour is also a little broken. Outcome: a future event then experiences the "all visible" DOM state.

In a React app, resizing the browser window causes a parent component to re-render and the child component(s) (e.g., <PaymentOption {...paymentProps} />) to re-render as well, even though the child’s content should not change with layout changes.

MUI DataGrid row height remained static, causing the tag elements in a custom renderCell to be cut off when there were many tags. The cell content needed to wrap and expand vertically based on tag count.

Konva Stage requires numeric width and height, but the parent container uses dynamic responsive sizing (e.g., percentage width with a resizable sidebar). Attempting to set dimensions via state/reference did not update reliably, causing incorrect or one-step-late rendering.

Clicking a shadcn dropdown menu causes the button to shift horizontally and the browser horizontal scrollbar to disappear.

Newly added UI elements always appear at the top of the window and ignore attempts to change their positions, preventing the intended inline button layout.

A full-screen loading overlay using `fixed inset-0` covered the entire viewport — including the fixed sidebar/navbar. Tension: making it inaccessible during loading. Outcome: The desired behavior was for the overlay to cover only the main content area while leaving the sidebar interactive.

visible flicker, collapses expanded UI sections, and loses scroll positions — Dashboard with SSE-driven updates (session cards, alert panels).

Tension: attacker-controlled sizes from PAX extended headers. Outcome: triggering a SIGSEGV/stack exhaustion.
