Not sure what you mean, but maybe this will help.
If you do `M-x customize-group Icicles' you see this:
,----
| Parent groups: dabbrev recentf convenience minibuffer
| completion matching apropos help
|
| Icicles group:
| State : visible group members are all at standard values.
| Minibuffer input completion and cycling of completion candidates.
| See also Doc-Part1, Doc-Part2, Description, Download,
| Other Libraries by Drew, and Send Bug Report.
|
| Subgroups:
| Icicles-Buffers Preferences related to buffers.
| Icicles-Completions-Display Preferences related to display of
| completion candidates.
| Icicles-Files Preferences related to files.
| Icicles-Key-Bindings Preferences related to key bindings.
| Icicles-Key-Completion Preferences related to key completion.
| Icicles-Matching Preferences related to matching input
| for completion.
| Icicles-Minibuffer-Display Preferences related to minibuffer
| display during completion.
| Icicles-Miscellaneous Miscellaneous preferences.
| Icicles-Searching Preferences related to searching.

You can define a subgroup by specifying the group
you want to be its parent as one of _its_ groups.
E.g., the `defgroup' of `Icicles-Matching' has
`:group 'Icicles', which means it's a subgroup
of group `Icicles'.
(defgroup Icicles-Matching nil
"Icicles preferences related to matching input for completion."
:prefix "icicle-" :group 'Icicles)
Then, a particular `defcustom' or `defface' can
specify which groups apply to it. E.g.:
(defcustom icicle-file-sort nil
"*A sort function for file names, or nil.
Examples of sort functions are `icicle-dirs-first-p',
`icicle-latest-access-first-p', and
`icicle-latest-modification-first-p'.
If nil, then file names are not sorted."
:type '(choice
(const :tag "None" nil)
(function :value icicle-dirs-first-p))
:group 'Icicles-Files :group 'Icicles-Completions-Display)
^^^^^^ ^^^^^^
The groups are defined in file `icicles-face.el'.
