In Sitecore, the “Insert option” allows you to create new items within a particular item or folder.
It adds a new child item to the existing parent item.
When you select “Insert” from the content editor, you can choose from a list of templates that determine the type of item you want to create, such as a page, a news item, or a product. The new item will inherit the security settings and field values from its parent item, but you can modify these as needed.
The “Insert option” is a useful way to quickly create new items within your Sitecore content tree, while maintaining the desired structure and consistency.
