Usage

// 1. Create/manage PickerState in your app state
// 2. Filter your items externally based on state.search
// 3. Compute detail lines for state.selected item
// 4. Call render_picker each frame

let filtered: Vec<PickerItem> = all_items
    .iter()
    .filter(|i| i.label.to_lowercase().contains(&state.search.to_lowercase()))
    .cloned()
    .collect();

let detail = if let Some(item) = filtered.get(state.selected) {
    vec![Line::from(item.label.clone())]
} else {
    vec![]
};

let area = tui_kit::popup::centered_popup(f, 0.88, 120, 30);
render_picker(f, area, "Find instance", &state, &filtered, detail, &theme);
