Join

Merges its children into one seamless segmented group.

Real use · segmented range picker

Input + button

Vertical

Using Join

Silica ships one design system through three paths. They share a class vocabulary but are not interchangeable — pick the one that matches what you are building.

Plain HTML — CSS classes

The Tailwind v4 plugin. Works in any framework or none — Rails, Django, PHP, Go, a static file. This path is complete for Join — it needs no JavaScript, so the classes below are the whole story.

/* in your CSS */
@import "tailwindcss";
@plugin "@wizeworks/silicaui";

Root class join, with 1 modifier:

.join
.join-vertical

React

Typed components over those same classes, with behavior and accessibility from Base UI.

npm i @wizeworks/silicaui-react

import { Join } from "@wizeworks/silicaui-react";

Props

Prop	Type	Required	Description
orientation	JoinOrientation	no	horizontal (default) or vertical.

Source of the demo above

The exact file that renders the examples above, so it can never drift from them. It imports a few of this site’s own layout helpers (../lib/…), so read it for the component calls rather than copying it whole.

import { useState } from "react";
import { Join, Button, Input } from "@wizeworks/silicaui-react";
import { Section, Row } from "../lib/Section";

const RANGES = ["Day", "Week", "Month"];

export function JoinDemo() {
    const [range, setRange] = useState("Week");

    return (
        <>
            <Section title="Real use · segmented range picker">
                <Join>
                    {RANGES.map((r) => (
                        <Button
                            key={r}
                            variant={r === range ? "solid" : "outline"}
                            color={r === range ? "primary" : "neutral"}
                            onClick={() => setRange(r)}
                        >
                            {r}
                        </Button>
                    ))}
                </Join>
            </Section>

            <Section title="Input + button">
                <Row>
                    <Join>
                        <Input placeholder="Search…" />
                        <Button color="primary">Go</Button>
                    </Join>
                </Row>
            </Section>

            <Section title="Vertical">
                <Join orientation="vertical" className="w-32">
                    <Button variant="outline" color="neutral">
                        Top
                    </Button>
                    <Button variant="outline" color="neutral">
                        Middle
                    </Button>
                    <Button variant="outline" color="neutral">
                        Bottom
                    </Button>
                </Join>
            </Section>
        </>
    );
}

Vanilla — node tree to HTML

Join — lowers to <div>, holding its children. Build a node tree, project it with toHtml(), and let the zero-dependency runtime hydrate it. This is the path for generated or user-authored documents — a site builder, CMS output, a static export.

npm i @wizeworks/silicaui-html @wizeworks/silicaui-behaviors

import { atom, toHtml } from "@wizeworks/silicaui-html";

const node = atom("Join", "join", { /* props */ }, [/* children */]);
const markup = toHtml(node);

Styling on this path is the class string in the second argument — the same classes as the Plain HTML section above. There is no color prop here; write "join join-primary" rather than passing a colour as a prop.

Takes children: yes
Hydrated by: nothing — this one is static markup

The full API for Join, on every path, is available through the Silica MCP server.
