A rail that was open over the page left it on `transition: … display … allow-discrete`: the compact adaptive rail's slide-out, the slide-out of a rail that hides when collapsed, and every rail scrim's fade. Firefox does not transition `display`, even with `allow-discrete` (Chrome 117 and Safari 18 do), so there the panel and the scrim vanished on the first frame. Unlike the sheets' scrims these are drawn by attribute rules on `data-md-open`, not `x-show`, so Alpine had nothing to hold. navigation.js now marks a rail that closes `data-md-closing` — `sheet` when the panel leaves the window, `scrim` when it stands in the layout again — and drops it once the panel's `translate` and the scrim's `opacity` transitions have finished (at once under reduced motion, or when the rail opens again). navigation-rail.css keeps what is leaving displayed, and a sliding panel in its open geometry, while the attribute is set, and no longer transitions `display` anywhere, so Chrome and Safari do not hold a second time. The view sets it from `x-effect`, beside the `x-bind` that drops `data-md-open`, so both attributes change in one flush: a `$watch` a microtask later let a style read in between settle the scrim as already hidden. The collapsed branches and `--md-navigation-rail-value` are untouched. NavigationTest samples each exit part-way in the page (the compact slide, the hide-when-collapsed slide, a modal rail's scrim) and checks it ends hidden; all three fail on main in Firefox and pass in Chrome, Firefox and Safari. They wait for the entry to finish first: Firefox creates a transition on its next refresh tick, so straight after a change its computed style already reads the end value. NavigationRailTest pins the holds and that no rule transitions `display`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

{{-- M3 Expressive's navigation rail: destinations down the start edge of a `medium` or wider

`mode` says what decides its width:
|
||
- `collapsed` — always collapsed; `expanded` — always expanded.
|
||
- `collapsible` (the default) — the visitor's choice: expanded until the menu button collapses
|
||
it. The choice is `$store.rail`, remembered in localStorage and applied by <x-theme-script>
|
||
before the first paint (<html data-rail>), so the rail never paints wide and snaps shut.
|
||
- `modal` — collapsed in the layout; the menu button (or `$store.rail.show()` from anywhere)
|
||
opens it expanded over a scrim, holding focus until Escape, the scrim, the menu button or
|
||
leaving the page closes it (Compose's ModalWideNavigationRail).
|
||
- `adaptive` — what `<x-scaffold>` uses, one rail per M3 window size class: on a compact
|
||
window (below `medium`, 600px) nothing until `$store.rail.show()` slides it in as a modal;
|
||
at `medium` (600–839) collapsed in the layout, opening as a modal; at `expanded` (840–1199)
|
||
a standard rail, collapsed until its menu button expands it in place; from `large` (1200)
|
||
the same standard rail, expanded to begin with. A visitor who has used the menu button keeps
|
||
that choice in both standard bands.
|
||
|
||
Slots: `brand` beside the menu button, only while expanded; `header` under it — one
|
||
`<x-fab label="…" icon="…">`, which the rail morphs: the label's width springs open and shut
|
||
with the rail, so the FAB becomes an extended FAB and back rather than one being swapped for
|
||
the other, and its label names it at both widths. It also rests flat, because M3 puts a FAB
|
||
nested in another component at elevation 0, not the 3 a standalone one has. Then the
|
||
destinations in the default slot, which alone scroll when the window is too short, and
|
||
`footer`, pinned to the foot. Header and footer never scroll, so nothing in them is cut off by
|
||
the scroller's edge.
|
||
|
||
Anything else inside takes both shapes from the rail's value: the rail publishes M3's two
|
||
(Compose's WideNavigationRailValue) as `--md-navigation-rail-value`, `collapsed` or
|
||
`expanded`, from the first paint and in step with the rail's own items, and every descendant
|
||
inherits it, so an application's CSS asks a style query instead of repeating the conditions:
|
||
|
||
@container style(--md-navigation-rail-value: collapsed) {
|
||
.account-summary { display: none; }
|
||
}
|
||
|
||
A rail open over a scrim reads `expanded`; outside a rail the property is unset and neither
|
||
value matches. Style queries on a custom property need Chrome 111, Safari 18 or Firefox 151.
|
||
The package's own rules write the conditions out (resources/css/components/navigation-rail.css
|
||
lists them), and tests/Feature/Components/NavigationRailTest.php keeps each copy to the same
|
||
conditions. Nothing that shows while collapsed may be wider than 96px.
|
||
|
||
Props: `label` names the landmark ("Main"); `width` is the expanded width (`256px`, held
|
||
between M3's 220 and 360dp) — or the word `narrow`, M3's other *collapsed* width
|
||
(NavigationRailCollapsedTokens.NarrowContainerWidth, 80px against the default 96), where the
|
||
items are their icons alone because no label fits under a 56px indicator at that width; the
|
||
labels stay in the accessibility tree, since they are what name the destinations, and a
|
||
narrow rail expands to the default 256px; `align` is `top` (the default) or `center`, which
|
||
puts the destinations at the rail's vertical centre — M3 prefers that on a tablet, for reach —
|
||
while the menu button, the brand and the FAB stay at the top and the footer at the foot, as M3
|
||
asks; more destinations than fit go back to the top rather than out of reach above the
|
||
scroller; `hide-when-collapsed` is M3's other expanded behaviour, for a `collapsible` or
|
||
`adaptive` rail: collapsing it takes it out of the layout altogether instead of narrowing it
|
||
to 96px, and it comes back expanded over a scrim when something calls `$store.rail.show()` —
|
||
a menu button in the app bar, which is the only way back, so put one there. Its own menu
|
||
button then docks it into the layout again. Not below `medium` for a collapsible rail, nor at
|
||
`medium` for an adaptive one: there it is the window and not the visitor that collapses a
|
||
rail, and M3's collapsed rail may never hide; `menu` shows the menu button (by default for `collapsible`,
|
||
`modal` and `adaptive`); `divider` draws M3's optional vertical divider on the edge the page
|
||
is on — which is also what M3 asks for when a page scrolls underneath a fixed rail; `fill`
|
||
(`false`) drops the container colour for a transparent rail over the page's own background,
|
||
which M3 allows as long as the items keep a 3:1 contrast against what is behind them. A rail
|
||
open over a scrim keeps its fill and drops the divider whatever those say: it is a surface
|
||
over the page then. As it closes it keeps `data-md-closing` (`sheet` while the panel slides off
|
||
the window, `scrim` while only the scrim fades) until the exit has run, which is what holds it
|
||
on screen in Firefox, where `display` cannot transition (resources/js/navigation.js). The rail
|
||
does not scroll with the page: in a flex row it sticks to the top of the viewport, as tall as
|
||
the viewport at most.
