I’m fairly new to Omeka S, using version 4.0.4.
How do I add items to an item set? Do I add them in the Relation field?
How do I display my item sets in the end-user interface. So far I am just using the default interface and have not applied any themes. Do I have to apply a theme to see my item sets?
The documentation for Item Set is located here: Item Sets - Omeka S User Manual
Once your item set is created, you can add your items via batch edit: Items - Omeka S User Manual or individually as you create items: Items - Omeka S User Manual
In sites, individual items show the sets with which they are associated.
When you edit your navigation you can also add a Browse Item Sets custom link to show the sets associated with your site: Navigation - Omeka S User Manual
Thank you! This is very helpful.
