Are Layout Directives supported by Angular 2 Material Design Components?
January 2017 Update:
Angular 2 team recently added a new NPM package flex-layout for layout only. It is a separate package independent of angular material.
The full instructions are available in the github page README.
Install the module:
npm install @angular/flex-layout -save
In app.module.ts (or equivalent), declare the module:
import {FlexLayoutModule} from "@angular/flex-layout";@NgModule({ imports: [ ... FlexLayoutModule ], ...})
Markup example:
<div class="flex-container" fxLayout="row" fxLayout.xs="column" fxLayoutAlign="center center" fxLayoutAlign.xs="start"> <div class="flex-item" fxFlex="20%" fxFlex.xs="40%"> </div> <div class="flex-item" fxFlex> </div> <div class="flex-item" fxFlex="25px"> </div></div>
Here is a plunker sample taken from the flex-layout github page.
Original Answer:
The docs you are referring to are for angular1 material. Angular2 material still doesn't have any layout directives.
You can easily create the directive yourself in a simple way.
All you need to know:
layout="row"
is same as style="display:flex;flex-direction:row"
layout="column"
=> style="display:flex;flex-direction:column"
And flex
is equal to style="flex:1"
As directives:
@Directive({ selector:'[layout]'})export class LayoutDirective{ @Input() layout:string; @HostBinding('style.display') display = 'flex'; @HostBinding('style.flex-direction') get direction(){ return (this.layout === 'column') ? 'column':'row'; }}
The flex directive, use it like: <div flex>
or <div flex="10">
any number from 0 - 100%. Also, just for fun, I added shrink and grow inputs
@Directive({ selector:'[flex]'})export class FlexDirective{ @Input() shrink:number = 1; @Input() grow:number = 1; @Input() flex:string; @HostBinding('style.flex') get style(){ return `${this.grow} ${this.shrink} ${this.flex === '' ? '0':this.flex}%`; }}
To use them everywhere without adding them to each component:
@NgModule({ imports: [ BrowserModule ], declarations: [ AppComponent,FlexDirective ,LayoutDirective ], bootstrap: [ AppComponent ]})export class AppModule { }
Here is a sample in plunk
No need to write a new directive until Material2 provide us the LayoutModule.
You just have to import the angular layouts-attributes.css from angular1.It takes the old directive as css selector.
require('node_modules/angular-material/modules/layouts/angular-material.layouts-attributes.css')
for example the css for directive layout-align="end" it use the cssselector: [layout-align="end"]
Another option is to use angular2-polymer in order to pull in Polymer's iron-flex-layout. It is slightly more limited and has a slightly different API than the Material 1 layout (but the Material 2 layout will also have a different API). But it works now and is supported.
