Conditional layouts - support for multi-select picklists

Conditional layouts - support for multi-select picklists

Hi,

The documentation for conditional layouts says the following:
"Layout Rules cannot be used on the following field types:
  1. Auto Number
  2. Lookup
  3. Multi Select Lookup
  4. User Lookup
  5. Formula
  6. File Upload
  7. Multi Line"
I have a custom module with a multi-pick list that I am trying to use to create a conditional layout, but the Layout Rule dialog won't display my multi pick list as an option for the primary field to control the rule.

Is the support document inaccurate?
