Hi. There is no settings for this, and most likely never will exist. But this is possible through CSS.
Why, I think that there will never be such settings? SP Page Builder works inside Component Area and can not affect the joomla template. The Joomla template is the main culprit that Position: Sticky does not work, but not SP Page Builder.
The presence of overflow (-x, -y): hidden, in the template, for any parent element destroy the operation of the Position: Sticky property.
For example, in Helix it is:
.body-innerwrapper {
overflow-x: hidden;
}
In order to force Position: Sticky working at the global level you need to override this code in this way:
.body-innerwrapper {
overflow-x: visible;
}
But this may cause a side effect in the form of horizontal scrolling when using animation and in some other cases.
Since SP Page Builder is designed to work in any templates and cannot affect their code, this option may not work for most templates. Therefore, the developer team is unlikely to implement it.
Elementor from your video creates its own page template. Therefore, it works there. But this approach is not very convenient in many more significant cases than using Position: Sticky. WordPress users complain of all these more important things which are not available due to constructive features of Elementor.
In addition, WordPress construction is different from Joomla. There are no templates and modules, there are Themes and plugins - that completely different construction.
Everywhere there are its pros and cons. And you need to choose that it is more important for you - some minor decoration opportunities or global functions.
You can try to use interections to achieve something similar as in the video.
And I repeat, you can make work Position: Sticky through CSS.
