I am interested in building an accordion feature in angular2 without needing to duplicate the structure each time it is used. Similar to how we can create plugins in jQuery and include HTML code, I would like to find a way to achieve this in Angular2. Can anyone provide guidance on how to approach this?
If you're looking for a way to incorporate Bootstrap components into your Angular project, one option is to utilize the "Angular powered Bootstrap" framework. Detailed instructions on how to install this can be found here.
This particular project offers an array of open-source Angular components that are designed to seamlessly integrate with bootstrap elements by using html-tags prefixed with <ngb-....
To illustrate this functionality, let's imagine creating a custom component named TopicTreeComponent, which visualizes instances of Topic within an accordion structure.
In this hypothetical scenario, we have a simple Topic class defined as follows:
export class Topic
{
public title;
public text;
...
}
To implement the corresponding TopicTreeComponent class:
@Component({
selector: 'topic-tree',
templateUrl: './topictree.component.html',
styleUrls: ['./topictree.component.css']})
export class TopicTreeComponent
{
public topics: Topic[] = ... ;
}
The view associated with TopicTreeComponent could resemble the following structure:
<nav>
<ngb-accordion #acc="ngbAccordion"
activeIds="ngb-panel-0"
closeOthers="true">
<ngb-panel *ngFor="let topic of topics">
<ng-template ngbPanelTitle class="bg-inverse">
{{topic.title}}
</ng-template>
<ng-template ngbPanelContent>
{{topic.text}}
</ng-template>
</ngb-panel>
</ngb-accordion>
</nav>
This code snippet effectively showcases how the TopicTreeComponent iterates over topics, displaying their respective titles and texts.
Also worth noting is the usage of the NgbAccordion component, which comes with its own set of documentation available here.
