Angular Material 7 provides an Expansion Panel component that helps to manage content visibility in a page or section. The Expansion Panel component is a container that provides extra information for the user in a collapsed or expanded mode. This component is useful when we want to reduce the visual complexity of a page, especially when displaying complex data.

An Expansion Panel consists of a header and a body. The header is the element that the user interacts with to expand or collapse the panel. The body is the content that is revealed when the panel is expanded. Angular Material 7 provides a set of CSS classes that we can use to customize the Expansion Panel according to our needs.

To use the Expansion Panel, we need to import the MatExpansionModule from @angular/material:

import { MatExpansionModule } from '@angular/material/expansion';

@NgModule({
  imports: [MatExpansionModule],
  ...
})
export class MyModule { }

Once we have imported the MatExpansionModule, we can use the component to define an Expansion Panel.


  
    
      
        This is the expansion panel title
      
      
        This is the expansion panel description
      
    
    

This is the expansion panel body

In the above example, we have an Expansion Panel with a header that has a title and a description. When the user clicks on the header, the panel expands to show the body content.

Angular Material 7 provides additional options that we can use to customize the Expansion Panel. For example, we can add an icon to the header, we can disable the panel, or we can set the panel to be expanded by default. We can also listen to events triggered by the Expansion Panel, such as when the panel is expanded or collapsed.

Overall, the Expansion Panel is a useful component that can help us to manage content visibility in a page. It is easy to use and customize, which makes it a good choice for complex web applications that need to display a lot of data in a user-friendly way. 免责声明:本文内容通过AI工具匹配关键字智能整合而成,仅供参考,火山引擎不对内容的真实、准确或完整作任何形式的承诺。如有任何问题或意见,您可以通过联系service@volcengine.com进行反馈,火山引擎收到您的反馈后将及时答复和处理。
