Dataselect - content not showing
I'm trying to implement the dataselect field type as per the tutorial here: https://solutions.grabaperch.com/templates/how-do-i-reuse-content-in-a-select-list
I can see the drop down on the page admin but theres no options - its just empty.
I guess it can't find the source data, but I'm not sure how to correct this. Any suggestions on what might be a common mistake here?
