Responsive grid that fits as many columns as its inline size allows — no media queries. Composes
|
|
|
through <a href="/uix/components/grid"><Grid></a> (and therefore
|
|
|
<a href="/uix/components/box"><Box></a>), so every Grid / Box prop still works.
|
|
|
<code>minChildWidth</code> drives the fluid template; <code>columns</code> falls back to a
|
|
|
fixed grid when that's the simpler fit. Eidos-native: no soma backing, no semantic events.

AutoGrid adds two props on top of <code><Grid></code>. When both are set,
|
|
|
<code>minChildWidth</code> wins — the fluid template is the AutoGrid use case.
|
|
|
<code>templateColumns</code> from Grid is intentionally not exposed: passing it would
|
|
|
conflict with AutoGrid's own computation; use <code><Grid></code> directly when a
|
|
|
custom track list is required.

children; it does not commit, emerge, or react to anything. Components that animate items

on enter/exit should compose AutoGrid with an interactive primitive (popover, drawer,

collapsible) that owns the relevant sema verbs.

Recipe lives in <code>src/uix/eidos/components/auto-grid/auto-grid.css</code>. AutoGrid
|
|
|
delegates every visible style to the Grid recipe; the file declares only the
|
|
|
<code>[data-auto-grid]</code> marker so consumers can target it directly. The fluid /
|
|
|
fixed template is computed in JS and emitted as <code>--grid-template-columns</code>.
