Angular collapse not resizing correctly

Topic: Angular collapse not resizing correctly

Alberto pro asked 7 years ago

Hello, the Angular collapse panel is not resizing correctly when the data to display comes from the component. It works correctly with static content but that kind of defeats the whole angular project. I had to resort to using the mat-accordion control from angular material to have a working collapsible panel. Please advise as when the bug will be fixed as i don't want a million different frameworks for may app. Cheers, Alberto

Hi Alberto, looking into this. Will come back to you as soon as we will get more information on that. Could you please meanwhile provide us with the input data which you use? Are they anyhow specific? Long strings etc?

Hi, it's just a paragraph of user comments retrieved with an observable e.g. Toggle collapse {{card.userComment}}

Dear Alberto, could you please share this sample via email : d.adach@mdbootstrap.com or some pastebin ? I am not sure what card.userComment is about

Alberto pro commented 7 years ago

The angular component exposes an array collection of objects as in data = Array. It is populated in ngInit by calling a service and subscribing to the returned Observable collection. The CardObject is a POCO that exposes several properties including userComment. Does this clarifies a bit? Cheers, Alberto

Dear Alberto, can you call resize() after populating comments ? What is the result?

Hi Alberto, please try this, update collapse.driective.ts with the following function:

public resize():void {
constcontainer=this._el.nativeElement;
this.maxHeight=this._el.nativeElement.scrollHeight;
this._renderer.setElementStyle(container, 'height', this.maxHeight+'px');
}

And once after updating the content, please call the following function. i.e. :

@ViewChild('test') myCollapse;
[...]

this.myCollapse._el.nativeElement.innerHTML='Anim pariatur ....';
this.myCollapse.resize();

This will set the height of the new collapse to a proper size.
