### Basic Allotment Implementation

Source: https://github.com/johnwalley/allotment/blob/main/website/docs/getting-started.md

A minimal example showing how to render two panes within an Allotment container. Ensure the library CSS is imported for correct styling.

```tsx
import * as React from "react";
import ReactDOM from "react-dom";
import { Allotment } from "allotment";
import "allotment/dist/style.css";

function App() {
  return (
    <Allotment>
      <div>Pane 1</div>
      <div>Pane 2</div>
    </Allotment>
  );
}

ReactDOM.render(<App />, document.querySelector("#app"));
```

```bash
npm run build
```

--------------------------------

### Allotment with Default Sizes

Source: https://github.com/johnwalley/allotment/blob/main/README.md

Set initial sizes for panes using the `defaultSizes` prop. Sizes will be scaled proportionally if their sum doesn't match the container size.

```jsx
<Allotment defaultSizes={[100, 200]}>
  <div />
  <div />
</Allotment>
```

--------------------------------

### Basic Allotment Usage

Source: https://github.com/johnwalley/allotment/blob/main/README.md

Import and use the Allotment component with basic content panes. Remember to import the default styles.

```jsx
import React from "react";
import { Allotment } from "allotment";
import "allotment/dist/style.css";

export const App = () => (
  <Allotment>
    <ComponentA>
    <ComponentB>
  </Allotment>
);
```

--------------------------------

### Configure Individual Panes

Source: https://github.com/johnwalley/allotment/blob/main/website/docs/getting-started.md

Use the Allotment.Pane component to define specific constraints like minimum size or snapping behavior for individual panes.

```tsx
import * as React from "react";
import ReactDOM from "react-dom";
import { Allotment } from "allotment";
import "allotment/dist/style.css";

function App() {
  return (
    <Allotment>
      <Allotment.Pane minSize={200}>
        <div>Pane 1</div>
      </Allotment.Pane>
      <Allotment.Pane snap>
        <div>Pane 2</div>
      </Allotment.Pane>
    </Allotment>
  );
}

ReactDOM.render(<App />, document.querySelector("#app"));
```

### Allotment.Pane API

Source: https://github.com/johnwalley/allotment/blob/main/website/docs/pane.md

Overview of the Pane component API for the Allotment library.

```APIDOC
## Pane

### Description
The Pane component is a structural element used within the Allotment layout system to define individual sections or panels.
```

--------------------------------

### Import Allotment CSS

Source: https://github.com/johnwalley/allotment/blob/main/website/docs/faq.md

Import the Allotment CSS at the root of your application to ensure proper styling. This is necessary for the component to render correctly.

```jsx
import "allotment/dist/style.css";
```

--------------------------------

### Allotment with Pane Component

Source: https://github.com/johnwalley/allotment/blob/main/README.md

Utilize Allotment.Pane for finer control over individual pane properties like minimum size and snap behavior.

```jsx
<Allotment>
  <Allotment.Pane minSize={200}>
    <ComponentA>
  </Allotment.Pane>
  <Allotment.Pane snap>
    <ComponentB>
  </Allotment.Pane>
</Allotment>
```

--------------------------------

### Allotment Pane Props

Source: https://github.com/johnwalley/allotment/blob/main/website/docs/pane.md

Configuration options for individual panes within the Allotment component.

```APIDOC
## Allotment Pane Props

This section details the properties that can be configured for each pane within the Allotment component.

### Props

- **maxSize** (number) - Optional - Maximum size of this pane. Overrides `maxSize` set on parent component.
- **minSize** (number) - Optional - Minimum size of this pane. Overrides `minSize` set on parent component.
- **priority** (`HIGH` | `NORMAL` | `LOW`) - Optional - Default: `NORMAL` - The priority of the pane when the layout algorithm runs. Panes with higher priority will be resized first. Only used when `proportionalLayout` is false.
- **preferredSize** (number | string) - Optional - Preferred size of this pane. Allotment will attempt to use this size when adding this pane (including on initial mount) as well as when a user double clicks a sash, or the `reset` method is called on the Allotment instance. The size can either be a number or a string. If it is a number it will be interpreted as a number of pixels. If it is a string it should end in either "px" or "%".
```

--------------------------------

### Programmatic Control of Allotment Component

Source: https://github.com/johnwalley/allotment/blob/main/README.md

Use a React ref to access the Allotment component instance for manual reset and resize operations. Ensure the ref is correctly attached to the Allotment component.

```jsx
const ref = React.useRef(ref);

return (
  <div>
    <button
      onClick={() => {
        ref.current.reset();
      }}
    >
      Reset
    </button>
    <button
      onClick={() => {
        ref.current.resize([100, 200]);
      }}
    >
      Resize
    </button>
    <Allotment ref={ref}>
      <div />
      <div />
    </Allotment>
  </div>
);
```

--------------------------------

## Allotment Component Props

### Description
Configuration properties for the Allotment component to control layout, sizing, and event callbacks.

- **minSize** (number) - Optional - Minimum size of any pane. Default: 30.
- **proportionalLayout** (boolean) - Optional - Resize each view proportionally when resizing container. Default: true.
- **separator** (boolean) - Optional - Whether to render a separator between panes. Default: true.
- **snap** (boolean) - Optional - Enable snap to zero for all panes. Default: false.
- **vertical** (boolean) - Optional - Direction to split. If true then the panes will be stacked vertically, otherwise they will be stacked horizontally. Default: false.
- **onReset** (func) - Optional - Callback that is fired whenever the user double clicks a sash.
- **onVisibleChange** (func) - Optional - Callback that is fired whenever the user changes the visibility of a pane by snapping.
