The columns of a grid as a list of lengths: the row shows the CSS it comes to, the editor holds one length per line with a picture of the shares above them. There is no reordering on purpose, because a track's place in the list is its place in the grid.
The import and the props worth knowing about, in one place.
import { InspectorTracks, tracksToCss } from "@/components/beste/component/inspector-tracks";
<InspectorTracks
label="Columns"
defaultValue={[
{ size: 1, unit: "fr" },
{ size: 2, unit: "fr" },
{ size: 240, unit: "px" },
]}
/>
<InspectorTracks
label="Rows"
value={rows}
onValueChange={setRows}
onOpenChange={(open) => console.log("editor open:", open)}
units={["fr", "px", "auto"]} // ["fr", "px", "%", "auto"] by default
minTracks={2}
maxTracks={6}
tone="outline" // "muted" (default) | "outline" | "ghost"
size="sm" // "sm" | "default" | "lg"
/>
// The value is only useful once it is a template, so the join ships with it
<div style={{ display: "grid", gridTemplateColumns: tracksToCss(columns) }}>{children}</div>Every one of these is in the component already. They are listed because a props table cannot mention a gesture, so nothing else on this page can tell you they exist.
| Up / Down | Step the focused track size |
|---|---|
| Shift + Up / Down | Step it by ten |
| Enter | Accept what was typed |
| Escape | Throw away what was typed, or close the editor |
Read from the component's own type, so this cannot drift from what it accepts.
