Dynamic options

Choice fields accept a static array or a callable. A dynamic callback is normalized and cached once per request by default.

pu_select('featured_page', function () {
    return [
        'home'  => 'Home',
        'about' => 'About',
    ];
}, ['label' => 'Featured page', 'searchable' => true]);

For WordPress entities, prefer the dedicated selectors (pu_post_select, pu_term_select, pu_user_select, etc.) instead of building repeated custom queries.
