Code: here i need if title matches in any hierarchy i need that menu in filteredModuel but with my code only any one coming.

1)in above response if i search for keyword “staf”

then i need [staff profile, staff leave, staff attendance]

2)if i search for “profil”

then i need [staff profile, student profile]

struct SearchView: View {
@State private var searchKeyword: String = ""
@State private var filteredModuel: [AppMenu] = []


@State private var selectedIndex: Int? = 4
@State private var navigateModule: Bool = false
@State private var moduleId: String = ""

var body: some View {
    ZStack {
        
        VStack(spacing: 0) {
            // in tabview i will show filterDataModuel()
            filterDataModuel()
            // some other code
        }
    }
    
    .onAppear {
        viewModelSidemenu.fetchAppLayout { success in
            filterDataModuel()
        }
    }
}


private func filterDataModuel() {
    let lowercasedKeyword = searchKeyword.lowercased()
    
    filteredModuel = []
    
    if let menus = viewModelSidemenu.layout?.menus {
        for menu in menus {
            let filteredChildMenus = menu.childMenus?.filter { childMenu in
                let childTitleMatches = childMenu.title?.lowercased().contains(lowercasedKeyword) ?? false
                return childTitleMatches
            } ?? []
            let titleMatches = menu.title?.lowercased().contains(lowercasedKeyword) ?? false
            
            if !filteredChildMenus.isEmpty {
                filteredModuel.append(contentsOf: filteredChildMenus)
            }
            if titleMatches && filteredChildMenus.isEmpty {
                filteredModuel.append(menu)
            }
        }
    }
}


@ViewBuilder func moduelView(moduel: AppMenu) -> some View {
    VStack {
        let urlStr = moduel.icon ?? ""
        URLImageView(url: urlStr, placeholder: "NoProfilePic", width: 100, height: 100, renderingMode: .template)
            .foregroundStyle(.black)
