Describe the bug
Radzen FilterPanelMenu not working correctly, because Something is missing in the function named Filter(string term) in the service (ExampleService) where the menu items are...

To Reproduce

I think the content of the function should be changed as follows

public IEnumerable<Example> Filter(string term)
        {
            if (string.IsNullOrEmpty(term))
                return allExamples;

            bool contains(string value) => value.ToLower().Contains(term.ToLower(), StringComparison.OrdinalIgnoreCase);

            bool filter(Example example) => contains(example.Name) || (example.Tags != null && example.Tags.Any(contains));

            bool deepFilter(Example example) => filter(example) || example.Children?.Any(filter) == true;

            return Examples.Where(category => category.Children?.Any(deepFilter) == true || category.Name.ToLower().Contains(term.ToLower()))
                            .Select(category => new Example
                            {
                                Name = category.Name,
                               //Expanded = true,
                               Expanded = category.Expanded,
                                Children = (category.Children == null) ? null : category.Children.Where(deepFilter).Select(example => new Example
                                {
                                    Name = example.Name,
                                    Path = example.Path,
                                    Icon = example.Icon,
                                   //Expanded = true,
                                   Expanded = example.Expanded,
                                    Children = example.Children
                                }
                                ).ToArray()
                            }).ToList();
        }

Expected behavior
For example, when I search for the word 'Dashboard' in the menu, it does not appear, and when I delete the search criteria, it appears expanded as if there were other items in the Dashboard.
