How to Show or Hide Accordion Item in .NET MAUI?

You can manage the visibility of an AccordionItem in MAUI Accordion by dynamically adding or removing items from the ViewModel bound collection.

This example demonstrates how to hide or show an accordion item using a button click event.

public class BehaviorExt: Behavior<ContentPage>
{
    Contact? deletedItem = null;
    SfAccordion? accordion;
    Button? button;
    protected override void OnAttachedTo(ContentPage bindable)
    {
        base.OnAttachedTo(bindable);
        accordion = bindable.FindByName<SfAccordion>("Accordion");
        button= bindable.FindByName<Button>("HideOrShow");
        button.Clicked += OnHideOrShow;
    }
    private void OnHideOrShow(object? sender, EventArgs e)
    {
        var items = (sender as Button)!.BindingContext as ContactViewModel;

        if (deletedItem == null)
        {
            deletedItem = items!.ContactsInfo![2];
            items.ContactsInfo.RemoveAt(2);
        }
        else
        {
            items!.ContactsInfo!.Insert(2, deletedItem);
            deletedItem = null;
        }
    }
}
