There are three required interfaces that have to be defined

protocol description
IMenuItem enum – menu categories
IListModel struct – list item model
IItemTpl struct – item view template

1. Enum

Define enum that conforming to IMenuItem. Protocol from package d3_menu_bar It is categories for the menu and list section headers

    import d3_menu_bar

    enum MenuItems: String, IMenuItem {

        case breakfast = "Breakfast"        
        case lunch = "Lunch"        
        case dessert = "Dessert"

2. Model

Define model that comforms to IListModel.

Add fields that you need in the List line representation

    struct ListModel : IListModel{
        let id = UUID()
        let category: MenuItems
        let title : String

3. Template

Define view for 2. Model that comforms to IItemTpl.

All representation of the template is up to you. It was included in component’s API on purpose to let easily control List representation via configuration.

    struct ItemTpl: IItemTpl {

        let item: ListModel

        var body: some View {

4. Create Auto scrollable header menu

    let data: [ListModel] = //Pass array of data
    ScrollableMenuList(items: data, content: { ItemTpl(item: $0) })
