Displaying widgets in footer on all pages with CodeIgniter 4

Question

As I'm having the same Header and Footer content accross all my pages, i'm using this code in the Views :

<?= $this->extend("layouts/default") ?> // this loads the header and footer
<?= $this->section("content") ?> 
<?= $this->endSection() ?>`

But how could I do to display data from database in the footer, so that it's displayed on all pages (it's a list of blog categories)

I don't know how to proper this, as I'm willing to avoid running queries in the view files.

THank you!
