Angular PrimeNG TieredMenu Inline

Angular PrimeNG是一个开源框架，拥有丰富的原生Angular UI组件，可用于出色的造型，这个框架用于制作响应式网站，非常容易。在这篇文章中，将看到如何在Angular PrimeNG中使用TieredMenu Inline。

TieredMenu Component允许用户以层级的形式制作菜单。TieredMenu内联允许用户在同一行内有嵌套的菜单项。

Angular PrimeNG TieredMenu内联属性：

• model。它是一个菜单项的数组。它的数据类型是数组，默认值是空。

语法:

<p-tieredMenu 
    [model]="gfg">
</p-tieredMenu>

创建Angular应用程序和模块安装。

第1步：使用以下命令创建一个Angular应用程序。

ng new appname

第2步：创建你的项目文件夹即appname后，使用以下命令移动到它。

cd appname

第3步在你给定的目录中安装PrimeNG。

npm install primeng --save
npm install primeicons --save

项目结构：完成安装后，它将看起来像下面这样。

• 运行下面的命令可以看到输出。

ng serve --open

例子1：下面是说明使用Angular PrimeNG TieredMenu Inline的例子代码。

<h5>PrimeNG TieredMenu Inline</h5>
<p-tieredMenu 
        [model]="gfg">
</p-tieredMenu>

import { Component } from "@angular/core";
import { MenuItem } from "primeng/api";
  
@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
})
export class AppComponent {
  gfg: MenuItem[];
  
  ngOnInit() {
    this.gfg = [
      {
        label: "JavaScript",
        items: [
          {
            label: "JavaScript1",
            items: [
              {
                label: "JavaScript1.1",
              },
              {
                label: "JavaScript1.2",
              },
            ],
          },
          {
            label: "JavaScript2",
          },
          {
            label: "JavaScript3",
          },
        ],
      },
      {
        label: "HTML",
        items: [
          {
            label: "HTML 1",
          },
          {
            label: "HTML 2",
          },
        ],
      },
      {
        label: "Angular",
  
        items: [
          {
            label: "Angular 1",
          },
          {
            label: "Angular 2",
          },
        ],
      },
    ];
  }
}

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule } 
    from "@angular/platform-browser/animations";
import { AppComponent } from "./app.component";
import { TieredMenuModule } from "primeng/tieredmenu";
  
@NgModule({
  imports: [BrowserModule, 
              BrowserAnimationsModule, 
              TieredMenuModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}

输出:
