Tech Writing - Field Dependency correct term here?

Hi,

Suppose (redacted example) I have an application to measure running statistics.

First field (UNITS) is a drop-down menu with the choices (MILES, KILOMETERS, OTHER)
The subsequent fields are determined by the first field.
If UNITS = MILES,:
    One field (Mi.) displays, with numeric input.
If UNITS = KILOMETERS
    One field (Km.) displays, with numeric input.
If UNITS = OTHER
    Two fields display:
        CUSTOM UNIT (text field to enter whatever you want (e.g. meters, furlongs, etc.)
        DISTANCE (where you enter a numeric value e.g. 3 for 3 furlongs).

Is it correct to say that there's a field dependency between the subsequent fields and UNITS? I've heard of that term used if a field's available values depend on some other field

but how about in this case? (I'm not using Salesforce, my friend Google found it. :) )

Thanks,
Steve

You can say field dependency in your context, or field prerequisite.  The second is older terminology and the former is more common terminology

Hi Steve,
Field Dependency (dependent fields) is a fine term, and another term for it is conditional field. Here's a discussion on it at a popular software product, Drupal:

@Joe - What can I say? I have fast fingers. Especially when I want to close out this issue so I can cook dinner. :)

PS-I love how you're both online on a Friday evening. Dedication.
