No worries. I was trying to figure out, given the data available. Where did you lose the trail? This isn’t critique of you, I’m genuinely interested in how my docs failed.
OK, it’s not possible to document every corner of the app as a complete self-contained description from first principles. But…
My assumption is that if someone sees a description of an attribute type they don’t understand they’d look it up. The app Help page on ‘Attributes’ says:
Lists are strings separated by semicolons, and are useful for lists of topics, categories, and tags.
My note on the List type starts:
A semi-colon delimited list of string values.
How might this info be easier to find? What sort of terms were you searching on?
