The 'Root Collection' is a special type of collection as it defines what the user sees first when opening the app. That's why the 'Root Collection' cannot be deleted.
However, all settings and uploads of content items are similar to those of normal collections.
You can access the Root Collection page on the Twixl platform via Content > Root Collection.
As the Root Collection is the first thing users will see, it is clear that this entry point defines your app's success as we want to attract the user to start using the app.
You can upload content items (also browse grid items) to your Root Collection directly. But we advise to think about Collection links, Content Item aliases... in stead of uploading the same content multiple times. If you ever need to change the content in a content item, you will only need to change this once if you link to that content item or collection via links and aliases.
Changing your Root Collection
In the life cycle of your app, you might need to update your Root Collection on a regular basis (e.g. new approach for the app). At that point, you can create a normal collection and add the new structure and links in there. After testing, you can decide to define that collection as the new Root Collection.
Go to Content > Root Collection > Collection Settings > Collection used > Change
You will get an extra warning explaining the consequences. The collection you select will be renamed to 'Root'. The former root collection will be renamed to 'Root - Before dd/mm/yyyy'.
After your final approval, the new Root Collection will be displayed. Make sure all your content items in it are set to 'published'!
