Showing and Hiding a Collapse without a variable

[Maaaxiii]

Hi there,

I was wondering if its possible to show and Hide an Collapse (in an Accordion) without having to define a dedicated bool.

The Documentation only shows an example with dedicated bools.

My Problem: I am generating a Collapse for each element in a List, so I am unable to define a dedicated bool. Is there any way I can still make my Collapse Visible and Invisible?

Thanks for your Help

No there is no way. Collapse is a pretty generic container/component and there is no other dedicated component that should act as close action for Collapse.

Maybe I should have checked before I posted an answer 😅

You have two ways of doing it actually.

1. Have @ref for collapse and then use Toggle(), eg. collapse.Toggle()
2. You can use the cascaded value from collapse(only if your other component is inside of Collapse).

  [CascadingParameter] public Collapse ParentCollapse { get; set; }
  
  void OnSomeClick()
  {
    ParentCollapse.Toggle()
  }
