Layout

Handling the overall layout of a page.

Specification#

Size#

The first level navigation is left aligned near a logo, and the secondary menu is right aligned.

Top Navigation: the height of the first level navigation 64px, the second level navigation 48px.
Top Navigation (for landing pages): the height of the first level navigation 80px, the second level navigation 56px.
Calculation formula of a top navigation: 48+8n.
Calculation formula of an aside navigation: 200+8n.

Interaction rules#

The first level navigation and the last level navigation should be distinguishable by visualization;
The current item should have the highest priority of visualization;
When the current navigation item is collapsed, the style of the current navigation item is applied to its parent level;
The left side navigation bar has support for both the accordion and expanding styles; you can choose the one that fits your case the best.

Visualization rules#

Style of a navigation should conform to its level.

Emphasis by colorblock
When background color is a deep color, you can use this pattern for the parent level navigation item of the current page.
The highlight match stick
When background color is a light color, you can use this pattern for the current page navigation item; we recommend using it for the last item of the navigation path.
Highlighted font
From the visualization aspect, a highlighted font is stronger than colorblock; this pattern is often used for the parent level of the current item.
Enlarge the size of the font
12px, 14px is a standard font size of navigations, 14px is used for the first and the second level of the navigation. You can choose an appropriate font size regarding the level of your navigation.

Component Overview#

Layout: The layout wrapper, in which Header Sider Content Footer or Layout itself can be nested, and can be placed in any parent container.
Header: The top layout with the default style, in which any element can be nested, and must be placed in Layout.
Sider: The sidebar with default style and basic functions, in which any element can be nested, and must be placed in Layout.
Content: The content layout with the default style, in which any element can be nested, and must be placed in Layout.
Footer: The bottom layout with the default style, in which any element can be nested, and must be placed in Layout.

Based on flex layout, please pay attention to the compatibility.

Header-Content-Footer

The most basic "header-content-footer" layout.

Generally, the mainnav is placed at the top of the page, and includes the logo, the first level navigation, and the secondary menu (users, settings, notifications) from left to right in it. We always put contents in a fixed size navigation (eg: 1200px), the layout of the whole page is stable, it's not affected by viewing area.

Top-bottom structure is conform with the top-bottom viewing habit, it's a classical navigation pattern of websites. This pattern demonstrates efficiency in the main workarea, while using some vertical space. And because the horizontal space of the navigation is limited, this pattern is not suitable for cases when the first level navigation contains many elements or links.

TypeScript
JavaScript
import { Breadcrumb, Layout, Menu } from 'infrad';
import React from 'react';

const { Header, Content, Footer } = Layout;

const App: React.FC = () => (

          return {
            key,
            label: `nav ${key}`,
          };
        })}
      />
    </Header>

Sider

Two-columns layout. The sider menu can be collapsed when horizontal space is limited.

Generally, the mainnav is placed on the left side of the page, and the secondary menu is placed on the top of the working area. Contents will adapt the layout to the viewing area to improve the horizontal space usage, while the layout of the whole page is not stable.

The level of the aside navigation is scalable. The first, second, and third level navigations could be present more fluently and relevantly, and aside navigation can be fixed, allowing the user to quickly switch and spot the current position, improving the user experience. However, this navigation occupies some horizontal space of the contents.

Responsive

Layout.Sider supports responsive layout.

Note: You can get a responsive layout by setting breakpoint, the Sider will collapse to the width of collapsedWidth when window width is below the breakpoint. And a special trigger will appear if the collapsedWidth is set to 0.

TypeScript
JavaScript
import { UploadOutlined, UserOutlined, VideoCameraOutlined } from 'infra-design-icons';
import { Layout, Menu } from 'infrad';
import React from 'react';

const { Header, Content, Footer, Sider } = Layout;

const App: React.FC = () => (
  <Layout>
    <Sider
      breakpoint="lg"
      collapsedWidth="0"
      onBreakpoint={broken => {
        console.log(broken);
      }}
      onCollapse={(collapsed, type) => {
        console.log(collapsed, type);
      }}
    >
      <div className="logo" />
      <Menu
        theme="dark"
        mode="inline"
        defaultSelectedKeys={['4']}
        items={[UserOutlined, VideoCameraOutlined, UploadOutlined, UserOutlined].map(
          (icon, index) => ({
            key: String(index + 1),
            icon: React.createElement(icon),
            label: `nav ${index + 1}`,
          }),
        )}
      />
    </Sider>
    <Layout>
      <Header className="site-layout-sub-header-background" style={{ padding: 0 }} />

      </Content>
      <Footer style={{ textAlign: 'center' }}>Infra Design ©2018 Created by Ant UED</Footer>
    </Layout>
  </Layout>
);

Fixed Header

Fixed Header is generally used to fix the top navigation to facilitate page switching.

TypeScript
JavaScript
import { Breadcrumb, Layout, Menu } from 'infrad';
import React from 'react';

const { Header, Content, Footer } = Layout;

const App: React.FC = () => (
  <Layout>
    <Header style={{ position: 'fixed', zIndex: 1, width: '100%' }}>
      <div className="logo" />
      <Menu
        theme="dark"
        mode="horizontal"
        defaultSelectedKeys={['2']}
        items={new Array(3).fill(null).map((_, index) => ({
          key: String(index + 1),
          label: `nav ${index + 1}`,
        }))}
      />
    </Header>
    <Content className="site-layout" style={{ padding: '0 50px', marginTop: 64 }}>
      <Breadcrumb style={{ margin: '16px 0' }}>
        <Breadcrumb.Item>Home</Breadcrumb.Item>
        <Breadcrumb.Item>List</Breadcrumb.Item>
        <Breadcrumb.Item>App</Breadcrumb.Item>
      </Breadcrumb>
      <div className="site-layout-background" style={{ padding: 24, minHeight: 380 }}>
        Content
      </div>
    </Content>
    <Footer style={{ textAlign: 'center' }}>Infra Design ©2018 Created by Ant UED</Footer>
  </Layout>
);

export default App;
#components-layout-demo-fixed .logo {

Fixed Sider

When dealing with long content, a fixed sider can provide a better user experience.

TypeScript
JavaScript
import {
  AppstoreOutlined,
  BarChartOutlined,
  CloudOutlined,
  ShopOutlined,
  TeamOutlined,
  UploadOutlined,
  UserOutlined,
  VideoCameraOutlined,

  CloudOutlined,
  AppstoreOutlined,
  TeamOutlined,
  ShopOutlined,
].map((icon, index) => ({
  key: String(index + 1),
  icon: React.createElement(icon),
  label: `nav ${index + 1}`,
}));

const App: React.FC = () => (
