Conditional layout templates

Your template can use include() to render the main content, and for your ajax call you can return only this view. See https://codeigniter4.github.io/userguide...w-partials

PHP Code:

<?= $this->extend('default') ?>

<?= $this->section('content') ?>
    <?= $this->include('main_content') ?>
<?= $this->endSection() ?>
