Final answer:
You can edit an item in the Experience Editor without presentation details set by adding new presentation details, including layout and renderings/sublayouts to placeholders, even though it's a more technical process requiring a good understanding of Sitecore’s structures.
Step-by-step explanation:
Yes, you can edit an item in the Experience Editor even when the item has no presentation details set. In Sitecore, presentation details define how an item is displayed on a page. However, if these details are not set, you can still enter the Experience Editor and add components to the item. The process would involve setting new presentation details for that item, which includes adding layout details and assigning renderings or sublayouts to the placeholder keys on the layout.
In cases where more than 100 word detail is needed, remember that adjusting presentation details is a common task during website development and content management in Sitecore. Beginning this process is straightforward, but you should understand the structure of the Sitecore content tree and the purpose of presentation details before making changes. This will ensure a smooth editing experience and help maintain the integrity of the site’s design and functionality.
