How to make a 3 tier accordion in WordPress?

Question

WordPress

Good afternoon!
I would like to know if there are any WordPress plugins to make such a 3-level accordion?

Or can somehow make a separate block on Elementor or WP Bakery?

Thanks in advance.

Ps I know that the menu can be done like this, but it usually opens to the side in templates, I need an accordion.

Answer 1

I think that an extra plugin will be superfluous. Try to do it in pure HTML

<details>
    <summary>Read more</summary>
    Some text to be hidden.
