if you have:
- A template with a dropdown (or droplink field)
- A second template with a checkbox field
You want to have: An item based on the first template with a dropdown where only items are displayed which have the checkbox checked.
My source is:
First you have to keep in mind that item names with “-” dashes should be covered by “#” else you get the exception: Invalid lookup source …
Second (if you operate with a second language – here: german): If you don’t get any results, mark the checkbox as shared. In some way the query doesn’t select the correct language from my point of view.
