Hi,
Ah ok, I see what you mean.
I can see that SP page builder made a similar capability for Joomla articles and JStore products (which uses Joomla articles as basis) for its PRO version.
However, making this work for HikaShop will require SP page builder to add that capability in SP page builder as far as I understand. I'm afraid asking us for it won't help as we can't do it from our end.
Now, if SP page builder needs our help to add that integration, we'll be happy to help, but I would recommend you ask them about that possibility.
Regarding alternatives to that, I must say that I'm not familiar with the capabilities of the different page builders out there so I wouldn't be able to say if that is possible with other page builders already or not.
From what I understand, yootheme pro has a source API available so that developers can develop integration plugins for that purpose:
yootheme.com/support/yootheme-pro/joomla/developers-sources
But there is no ready-made solution available for HikaShop. I can see several persons asked that to yootheme but seeing they released their own basic ecommerce solution, I doubt they'll do it.
However, while looking for information on page builders, I found this one:
www.joomlack.fr/en/joomla-extensions/page-builder-ck
It's a page builder that adds a button to the Joomla editor so that you can edit pages through its interface and add the pages built with the editor as a content tag in the content edited with the Joomla editor.
So this will work similarily to what you have already and it will work for Joomla articles, HikaShop products, etc. Basically, anything that can use a Joomla content editor.
And even better, it can work with any template out there. So I think this should be a nice alternative to JSN.
