// EmojiPicker: pick an emoji from tabs of categories (smileys, people, animals,// food, travel, activities, objects, symbols) or by searching their names. The// emoji are radio buttons, so the arrow keys move between them, and each is named// for screen readers ("grinning face"); the one picked goes in a hidden input// named `name`, so a plain <form> sends it.////   <EmojiPicker id="reaction" name="emoji" label="Reaction"/>//   <EmojiPicker id="status" label="Status" value="🌴" on_change={(e) => { status = e }}/>//// id: a prefix for its ids, unique on the page. value: the emoji picked to start// with. categories: the categories to show, in place of the eight built in// (`emoji_picker_sets`: a list of { label, emoji: [[emoji, name], ...] }).// search (true): the search box, which looks through every category. columns (8):// emoji per row. empty: what the grid says when nothing matches ("No emoji match").// label, hint, error and required as for every field. The tabs follow the ARIA// tabs pattern: the arrow keys, Home and End move between them.// on_change(emoji): inside one of your components, given the emoji picked.import ui/theme.qwe use ui_clslet emoji_picker_css = css`.ui-emoji-picker { display: grid;
