Besides automatic locations, you can drop a section exactly where you want it.
Archive Section block
In the block editor or Site Editor, add the Archive Section block and pick a section from the dropdown. It works in Full Site Editing templates, where shortcodes can’t go, and always shows the section’s current content.
Shortcode
Replace 123 with the section’s ID (shown in the edit screen URL). Use it in the classic editor, widgets or page builders.
Display controls still apply: Both the block and the shortcode respect scheduling, login state, devices, roles and the Active toggle.
