I’d like to know if I can “separate” the tabs from the RSS feed. For exemple, I’d like to put the tabs on a sidebar (with HTML code?) from my WP theme, and the RSS feed on the middle part of my page.
I don’t know if I’m clear…
Unfortunately the current implementation is that tabs and the RSS feed are bound together. That is tabs cannot be removed and placed elsewhere. It is to make a connection between the tabs and tab content.
This is because a page can have multiple RSS feed with tabs and implementation will get complicated. Plus, there were no requirements for the same.
However, using some CSS we can align the tabs to the left of the RSS feed like in the image but not have totally different position.
What you can do is, you can use some external tab plugin, visual builder or something like that and create the tabs on the sidebar then insert the shortcode for each RSS feed in each tab content.
