Components

Every component in the Solid kit, running. Not a screenshot of one anywhere: each block below is the real component, imported from @ui/* and rendered on this page. Use the sidebar to jump to a group.

They are ordinary Solid components: named exports, props in, an element out. Two things catch people out. Handlers keep their DOM names —{" "} onclick, oninput,{" "} onchange, never onClick. And many props accept a signal getter as well as a value, so you can pass{" "} value={"{"}name{"}"} rather than{" "} value={"{"}name(){"}"} and let the component track it.
Take the tour
); } // ---- buttons ------------------------------------------------------------- function Buttons() { const [clicks, setClicks] = createSignal(0); const [span, setSpan] = createSignal("week"); return (
Colour, outline, size and an optional icon. A button with an icon and no text gets square padding rather than the wide pill a text button gets — so an icon button is a square, not a lozenge with a picture rattling around in it.
Primary Green Red Blue Neutral White Light
Outline Danger Small + icon Disabled
setClicks(clicks() + 1)}> Clicked {clicks()} times // onclick, not onClick. These are DOM handler names.`} >
setClicks(clicks() + 1)}> Clicked {clicks()} times setClicks(0)}>Reset (a link that is a button) setClicks(0)}>And a destructive one
); } // ---- badges & alerts ----------------------------------------------------- function Badges() { return (
A badge is a solid fill with white text, so it stays legible in both themes without a variant on it. An alert is the opposite: a wash of colour behind dark text, which is exactly the case a token cannot carry into dark mode — a red-50 tint is invisible on a near-black surface — so alerts are one of only two places in the kit with a dark: rule.
active failed info pending default muted
An informational message with a header. A success alert, with no header. Something needs your attention. Something went wrong. And a neutral one. On the plain surface.
{/* It is absolutely positioned (top-0 -right-2), so it needs a relative ancestor to hang off — normally the logo. And it renders NOTHING in production, which is the whole point of it: a badge that is always there tells you nothing. */}
kjol

Nothing beside the wordmark? Then this build is production — which is what it is telling you.

); } // ---- cards & layout ------------------------------------------------------ function CardsAndLayout() { return (
The structural furniture: cards, headings, dividers, crumb trails, a spinner, a code box. Nothing here holds state — they are containers, and they take their children.
Card

Padded, and grows to fill its row.

BorderCard

A border instead of a shadow.

Cut corner

The same, with a clipped corner.

New} />
An external link (new tab)

FontAwesome, tree-shaken. The bundler scans the source for the names actually referenced, pulls just those paths out of the SVG kit, and emits a registry containing only them — which is why this site ships a few dozen glyphs rather than FontAwesome's 41.5 MB kit. A name nothing in the source references is not bundled; a name the kit has never heard of renders an empty box and is reported by the bundler rather than shipping silently.
{(name) => (
{name}
)}
IconContainer IconInline sits on the text baseline

The last two are the same name in the solid and regular styles. Which one you get by default is a CSS variable the app sets, read at runtime.

"That is not an email address." : ""); return (
Inputs are controlled: the value goes in as a prop, the change comes out as a callback, and the caller owns the state. The masked fields carry their behaviour inside the component — a currency field will not let you type a letter into it — which is the only reason it is the same in every app. email() && !isEmailValid(email()) ? "That is not an email address." : ""; setEmail(e.currentTarget.value)} error={emailError()} showIcon />`} >

); } // ---- selects & comboboxes ------------------------------------------------ const LANGUAGES = [ { value: "go", label: "Go" }, { value: "rust", label: "Rust" }, { value: "ts", label: "TypeScript" }, { value: "python", label: "Python" }, { value: "kotlin", label: "Kotlin" }, { value: "swift", label: "Swift" }, ]; const PEOPLE = [ { value: "ada@example.com", label: "Ada Lovelace" }, { value: "alan@example.com", label: "Alan Turing" }, { value: "grace@example.com", label: "Grace Hopper" }, { value: "katherine@example.com", label: "Katherine Johnson" }, { value: "margaret@example.com", label: "Margaret Hamilton" }, { value: "radia@example.com", label: "Radia Perlman" }, ]; function Selects() { const [one, setOne] = createSignal(""); const [many, setMany] = createSignal(["go"]); const [tags, setTags] = createSignal(["go"]); const [state, setState] = createSignal(""); const [tz, setTz] = createSignal(""); const [picked, setPicked] = createSignal(""); return (
A combobox picks one; a multi-select picks several, with checkboxes on the rows and removable pills in the field. Past three selections — or once the pills stop fitting — the field collapses to "N items selected" rather than growing until it wraps.

Two characters before it asks; 200 ms after you stop typing. A response for a query you have already typed past is DISCARDED rather than shown — which is the whole bug with hand-rolled autocompletes.

Tags ({tags().length}) } options={LANGUAGES} value={tags} onchange={setTags} searchable showSelectAll />

Same selection model as the field above; only the thing you click on differs.

); } // ---- toggles & signature ------------------------------------------------- function Toggles() { const [notify, setNotify] = createSignal(true); const [locked, setLocked] = createSignal(false); const [signed, setSigned] = createSignal(""); return (
A toggle is a checkbox that admits what it is — there is no{" "} FormCheckbox in this kit, and that is deliberate. The signature pad hands you back the drawing as an SVG string.

Draw in it. Clearing it emits an empty string, so "did they sign?" is just a length check.

); } // ---- dates --------------------------------------------------------------- function Dates() { const [date, setDate] = createSignal(""); const [dob, setDob] = createSignal(""); const [day, setDay] = createSignal(""); return (
The field is typeable, not merely clickable, and it parses loosely. A picker you can only click is a picker that is slower than the keyboard for everyone who already knows the date.

The same grid the picker drops down, usable directly when you want it inline. Pass{" "} variant="month" for the big version.

); } // ---- tables -------------------------------------------------------------- interface Institution { name: string; state: string; term: string; rate: number; minimum: number; status: "open" | "closed" | "waitlist"; } const ROWS: Institution[] = [ { name: "First Meridian Bank", state: "CA", term: "90 day", rate: 4.85, minimum: 1000, status: "open" }, { name: "Harborline Credit Union", state: "WA", term: "180 day", rate: 5.1, minimum: 2500, status: "open" }, { name: "Cascade Federal", state: "OR", term: "1 year", rate: 5.35, minimum: 500, status: "waitlist" }, { name: "Ironwood Savings", state: "IL", term: "90 day", rate: 4.6, minimum: 10000, status: "closed" }, { name: "Great Lakes Trust", state: "MI", term: "2 year", rate: 5.55, minimum: 1000, status: "open" }, { name: "Sunbelt National", state: "TX", term: "180 day", rate: 4.95, minimum: 5000, status: "open" }, { name: "Granite State Bank", state: "NH", term: "1 year", rate: 5.2, minimum: 2000, status: "waitlist" }, { name: "Pacific Crest", state: "CA", term: "5 year", rate: 5.75, minimum: 25000, status: "open" }, { name: "Copper Ridge Bank", state: "AZ", term: "90 day", rate: 4.4, minimum: 1000, status: "closed" }, { name: "Bayou Community", state: "LA", term: "1 year", rate: 5.05, minimum: 1500, status: "open" }, { name: "Northern Pine FCU", state: "MN", term: "2 year", rate: 5.45, minimum: 500, status: "open" }, { name: "Chesapeake First", state: "MD", term: "180 day", rate: 4.75, minimum: 3000, status: "waitlist" }, ]; // The whole AutoTable is this list.

Three of them, and the difference is what the user is allowed to do. PrettyTable prints rows. CellGrid lets them be edited in place. AutoTable filters, sorts, pages, reorders, resizes and exports — configured with a column list and an array of rows. Ada Lovelace Pro active Alan Turing Free trial Grace Hopper Enterprise invited setGridRows((rows) => rows.map((r) => (r.id === id ? { ...r, [field]: value } : r))) } sortKey={sortKey()} setSortKey={setSortKey} sortDesc={sortDesc()} setSortDesc={setSortDesc} />

Click a Qty or Price cell and type; Tab and the arrow keys move between editable cells. The grid does not own the rows — it tells you which cell changed and hands the value back.

AutoTable is the big one. Sort by clicking a header, drag a header to reorder it, use the toolbar to hide a column or export what you are looking at. The column layout is keyed to localStorage, so it survives a reload.
( ctx.setSearchValue("name", v)} /> ctx.setSearchValue("state", v)} /> )} rowRenderer={(item: Institution) => ( <> {item.name} {item.state} {item.term} {item.rate.toFixed(2)}% {money(item.minimum)} )} />
This table is passed data. Give it{" "} url instead and the same column list drives a server-side query — the sort identifier becomes the sort key, the search fields become query parameters, and pagination is handled for you. Nothing else on the page changes.

Tooltips, popovers, menus and modals — every one measured against the real viewport. A floating panel portals itself to document.body, positions from its trigger's bounding box, and flips or shifts when it would otherwise run off the screen. None of them needs a host or a portal root mounted anywhere. That is the difference from a modal library that makes you remember a <div id="portal">{" "} at the bottom of your index.html.
Top Right Instant

A tooltip that only answers to a mouse is a tooltip a keyboard user cannot read.

Click me

Click outside, or press Escape. Only the TOPMOST floating panel closes per press.

Aligned to my right edge

Placement bottom-end.

Hover, then reach the panel

Move the cursor across the gap and onto this panel — it stays open. Select this text to prove it. Without that grace period the panel would close in the dead space between the two, which is what happens once a panel is portaled and CSS :hover no longer reaches it.

Actions toast.success("Profile opened")}>Profile toast.info("Settings opened")}>Settings toast.info("Archived")}>Archive toast.warning("Duplicated")}>Duplicate toast.generic("Menu stayed open")}> Stay open (closeOnClick={"{false}"}) toast.error("Signed out")}>Sign out Opens on hover One Two

The items raise toasts, which is how you can see that an item really does close its own menu — and that the one marked closeOnClick={"{false}"} does not.

setModalOpen(true)}>Open modal setConfirmOpen(true)}> Delete something… setWizardOpen(true)}> Open wizard

Open the modal, then the nested one inside it, and press Escape twice: modals unwind ONE LAYER per press rather than all at once.

setModalOpen(false)} header={

A modal

Portaled to document.body, so no ancestor's{" "} overflow: hidden or transform can clip it — the two things that silently clip a floating panel.

Escape closes THIS one first, not the one behind it.

All set for {wizardName() || "nobody"}. Finish to close.

); }, }, ]} />
); } // ---- feedback ------------------------------------------------------------ function Feedback() { const toast = useToast(); const flash = createRemoteFlash(2000); return (
Toasts dismiss themselves after five seconds, with a bar counting down. A sticky one ( duration: null) waits for the user instead.
toast.success("Saved.")}> Success toast.error("Something went wrong.")}> Error toast.info("Just so you know.")}> Info toast.addToast({ message: "This one waits for you to dismiss it.", type: "warning", duration: null, }) } > Sticky (no timer)

useToast() throws outside a{" "} <ToastProvider> — which is one of only two providers this kit has.

Take the tour It dims the page, cuts a hole around each target, and animates the spotlight from one to the next. Targets are CSS SELECTORS — the same section ids the sidebar jumps to.
Something changed elsewhere

A brief acknowledgement that data you are looking at was changed by somebody else. It is not a toast: it belongs next to the thing that moved, not in the corner.

@ui/Chart draws SVG — no charting library, nothing vendored, no{" "} <canvas>. Because the picture is JSX it is already reactive: change series and Solid re-renders the marks that moved. There is no update() to call. Being SVG buys two things a canvas cannot. The marks name the theme tokens (var(--color-chart-1) …), so the palette inverts for dark mode with the rest of the site — a canvas paints pixels and cannot read a CSS variable. And every mark is a real element, so hovering shows a crosshair and one tooltip listing every series at that point.
setSeed(seed() + 1)}> New data setThreeD(!threeD())}> {threeD() ? "Flat" : "3D"} Each chart carries a title; a multi-series chart also draws a legend. Click a legend key — say Errors or a donut slice — to hide it, and the scale and marks recompute from what's left. The threeD prop gives every plot a 3D grid — bars extrude, a line or area draws flat over it, the donut tilts.

The same depth and tilt give the grid itself perspective: a floor recedes from the value-0 baseline into a back wall. Bars extrude into that space; a line or area stays flat on the front plane, drawn over the grid and read against the front axis — the stroke is not itself extruded, since depth on a hairline reads as noise.{" "} tilt runs 1 (head-on, near-flat) to 0 (bird's-eye);{" "} depth is the sweep length in px.

One kind prop picks the form —{" "} "line" | "area" | "bar" | "pie" | "donut" — and{" "} stacked, horizontal,{" "} curve, threeD{" "} (with depth / tilt),{" "} title, palette and{" "} valueFormat refine it. The legend it draws for a multi-series or pie/donut chart is interactive — clicking a key toggles that series or slice. The width is measured from the container, so a chart fills whatever column you give it.

horizontal runs the categories down the y-axis;{" "} stacked layers the series with a 2px surface gap between segments.

Press it. Every component on this page moves — none of them were told. Your choice is remembered, and it is the same choice Kjøl Wasm Web reads: both layers of this site share one kjol-theme key, so the theme survives crossing between two front-ends that share no code at all.

The swatch class is written out in full in the source, not built as{" "} "bg-" + name. Tailwind finds the classes it must compile by scanning the source for literal strings — a concatenation is invisible to it, and every swatch here would come out colourless.

Coloured tints

A red-50 wash is invisible on a near-black surface. An alert's tint has to become a deep, transparent one — a different colour, not a different value of the same one. One of only two places a{" "} dark: variant survives.

Fills that invert

The neutral button is dark on a light page and light on a dark one, so its label must invert with it — text-white would disappear the moment the fill went pale. Hence three tokens, not one. The other place.
