Usage

import React from "react";
import ReactDOM from "react-dom";
import { Layout, Panel } from "react-simple-dock";
import { DndProvider } from "react-dnd";
import { HTML5Backend } from "react-dnd-html5-backend";

const DEFAULT_CONFIG = {
    kind: "row",
    size: 100,
    children: [
        {
            kind: "column",
            size: 50,
            children: [
                { kind: "leaf", tabs: ["Panel 1"], tabIndex: 0, size: 50 },
                { kind: "leaf", tabs: ["Panel 2"], tabIndex: 0, size: 50 },
            ],
        },
        { kind: "leaf", tabs: ["Panel 3"], tabIndex: 0, size: 50 },
    ],
};

const App = () => (
    <div style={{ background: "#bdbdbd", width: "100vw", height: "100vh" }}>
        <Layout
            /* optional initial layout config */
            defaultConfig={DEFAULT_CONFIG}
        >
            <Panel key="Panel 1">
                <p>Content 1</p>
            </Panel>
            <Panel key="Panel 2" header={<i>Italic title</i>}>
                <p>Content 2</p>
            </Panel>
            <Panel key="Panel 3">
                <p>Content 3</p>
            </Panel>
        </Layout>
    </div>
);

ReactDOM.createRoot(document.getElementById("root") as HTMLElement).render(<App />);

Dynamic tab placement

When children are added/removed dynamically, Layout now preserves user-arranged layout and applies place only when a panel appears for the first time in the current layout.

<Layout
    defaultConfig={{
        kind: "row",
        children: [
            { kind: "leaf", tabs: ["Panel 1", "@anchor-1"] },
            { kind: "leaf", tabs: ["Panel 2"] },
        ],
    }}
>
    <Panel key="Panel 1">...</Panel>
    <Panel key="Panel 2">...</Panel>

    {/* Insert into the same tab list */}
    <Panel key="Panel 3" place={{ where: "after-tab", of: "Panel 1" }}>
        ...
    </Panel>

    {/* Insert as a sibling leaf around the target leaf */}
    <Panel key="Panel 4" place={{ where: "right", of: "@anchor-1" }}>
        ...
    </Panel>
</Layout>

• where supports: before-tab, after-tab, first-tab, last-tab, left, right, top, bottom.
• of references panel keys (or anchor tabs in defaultConfig, such as @anchor-1).
• If of is missing, placement falls back to the first tab currently present in the layout.
• Tabs prefixed with @ are treated as virtual anchors: preserved for placement, but never rendered as visible tabs or leaves.
