[Q] How do I add a submenu to settings app? - Android Q&A, Help & Troubleshooting

Hello guys!
I´m trying to add a submenu to my Rom. I allready open the apk with APKTool and edited some xmls with notepad++. But now I want to make a new submenu for all Halo settings, but how? Looking at other submenus don´t help!
The submenu xml looks like that at the moment:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen android:title="@string/halo_settings"
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="@string/halo_settings_header" android:key="halo">
<CheckBoxPreference android:title="@string/halo_hide_title" android:key="halo_hide" android:summary="@string/halo_hide_summary" android:defaultValue="false" />
<CheckBoxPreference android:title="@string/halo_reversed_title" android:key="halo_reversed" android:summary="@string/halo_reversed_summary" android:defaultValue="true" />
</PreferenceCategory>
</PreferenceScreen>

and the settings head like this:
