Module checklist 

The checklist: checkboxes in groups, one component for every screen.

A screen describes the list; the component decides how to present it from its size. Past SELECT_ALL_PAST choices it offers select all and none, past SEARCH_PAST a search box, and past COLLAPSE_PAST choices in more than one group it closes the groups that are settled (every choice ticked, or none) and opens the ones partly ticked. Each decision has an override: Checklist::select_all, Checklist::search, Checklist::expand.

use laterite_admin::checklist::{Checklist, Choice};
use laterite_core::Translator;

let html = Checklist::new("Topics")
    .choice(Choice::new("topic", "news", "News").checked(true))
    .group("Sport", vec![
        Choice::new("topic", "football", "Football").into(),
        Choice::new("topic", "cricket", "Cricket").note("Tests and one-day").into(),
    ])
    .render(&Translator::new("en"));
assert!(html.as_str().contains(r#"name="topic" value="football""#));

The markup works before any script runs: the boxes submit and the groups open and close. The checklist island adds the group boxes, the counts that follow the ticks, the search and the lat:checklist:changed event.
