Add this to your Styles:

<item name="android:listDivider">@android:color/transparent</item>

I had same problem with BottomNavigationView. Maybe someone will find my solution usefull.

Reason of this divider on android devices with API < 21 is this code snippet in BottomNavigationView sources:

if (VERSION.SDK_INT < 21) {
    this.addCompatibilityTopDivider(context);
}

addCompatibilityTopDivider(context) method:

private void addCompatibilityTopDivider(Context context) {
    View divider = new View(context);
    divider.setBackgroundColor(ContextCompat.getColor(context, color.design_bottom_navigation_shadow_color));
    LayoutParams dividerParams = new LayoutParams(-1, this.getResources().getDimensionPixelSize(dimen.design_bottom_navigation_shadow_height));
    divider.setLayoutParams(dividerParams);
    this.addView(divider);
}

My solution was to override design_bottom_navigation_shadow_color in colors.xml, like this:

<color name="design_bottom_navigation_shadow_color" tools:override="true">#00000000</color>

And it works:)

<group android:id="@+id/menu_top">
<item android:title="title1">
    <menu>
        <item
            android:id="@+id/nav_tab1"
            android:icon="@drawable/ic_action_nav_tab1"
            android:title="test1" />
        <item
            android:id="@+id/nav_tab2"
            android:icon="@drawable/ic_action_nav_tab2"
            android:title="test2" />
    </menu>
</item>
<item android:title="title2">
    <menu>
        <item
            android:id="@+id/nav_settings"
            android:icon="@drawable/ic_action_settings"
            android:title="test3" />
    </menu>
</item>

Try grouping these items...I haven't tried this but it should work
