# @react-md/layout

Create your app's layout and configure all of react-md in one place. There are eight different types of layouts supported that change automatically based on the window size and have reasonable defaults to get you started. The base layout will create a persistent navigation tree with a fixed header on desktop, while the navigation tree will be toggleable in a sliding sheet on mobile.

# Installation

npm install --save @react-md/layout

Since this package is more for general layout and configuration of components, it is highlight recommended to install the following packages as well:

npm install --save @react-md/app-bar \
  @react-md/button \
  @react-md/dialog \
  @react-md/icon \
  @react-md/list \
  @react-md/sheet \
  @react-md/states \
  @react-md/theme \
  @react-md/tooltip \
  @react-md/transition \
  @react-md/typography \
  @react-md/utils

# Usage

The main exports for this package are the Configuration component, Layout component, and useLayoutNavigation hook. The Configuration component should be mounted near the root of your app as it is a nice wrapper for all the required React Context providers to work within react-md.

123456789101112import React from "react";
import { render } from "react-dom";
import { Configuration } from "@react-md/layout";

import App from "./App";

render(
  <Configuration>
    <App />
  </Configuration>,
  document.getElementById("root")
);

Once your app has the base Configuration, you can create your base layout with the Layout component along with a navigation tree by using the useLayoutNavigation hook. The useLayoutNavigation hook requires you to pass your navItems along with the current pathname to work correctly. This means you'll want to get the pathname from your favorite routing library (react-router for example) so that the current route will automatically be selected.
