A vertical list of heterogeneous widgets with optional selection and scrolling.

Each item is a {widget, height} tuple where widget is any ExRatatui widget and height is the number of rows that item occupies. Items can have different heights, making this ideal for chat message histories.

Examples

iex> %ExRatatui.Widgets.WidgetList{}
%ExRatatui.Widgets.WidgetList{
  items: [],
  selected: nil,
  highlight_style: %ExRatatui.Style{},
  scroll_offset: 0,
  style: %ExRatatui.Style{},
  block: nil
}

iex> alias ExRatatui.Widgets.{WidgetList, Paragraph, Block}
iex> %WidgetList{
...>   items: [
...>     {%Paragraph{text: "First message"}, 1},
...>     {%Paragraph{text: "Second message"}, 1}
...>   ],
...>   selected: 0,
...>   block: %Block{title: "Chat", borders: [:all]}
...> }
