I am wondering how i can hide item's metadata in Exhibit when a field is empty.
I was able to do it in general collection according to instruction here -http://omeka.org/codex/Theme_API/show_item_metadata
But it didn't take effect in Exhibit.
I was able to hide empty fields in both general collection and exhibit by unchecking "Show Empty Elements" in general setting.
much easier than what i thought!
The Exhibit Builder plugin uses exhibit page views specified in the ExhibitBuilder/views/public and ExhibitBuilder/views/shared.
You would have to edit these views.
In particular, go to the ExhibitBuilder/views/public/exhibits/item.php file, as well as the other item.php files in the exhibit themes you use (ExhibitBuilder/views/shared/exhibit_themes/) and change the show_item_metadata parameters.
Let me know if this helps.
