I created a menu folder under res folder and, in that menu folder, I created a file called drawer_menu.xml. This is the text of that file:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view">
<group
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:checkableBehavior="single">
<item
android:id="@+id/nav_profile"
android:icon="@drawable/ic_profile"
android:title="Message" />
<item
android:id="@+id/nav_my_events"
android:icon="@drawable/ic_my_events"
android:title="Chat" />
</group>
<item android:title="Communicate">
<menu>
<item
android:id="@+id/nav_settings"
android:icon="@drawable/ic_settings"
android:title="Share" />
<item
android:id="@+id/nav_logout"
android:icon="@drawable/ic_logout"
android:title="Send" />
</menu>
</item>
</menu>
But the design view is white and blank. No element shows up.Also I don't get to see AppThemes option which usually shows up in layout xml files.

Try changing support libraries version to more stable as 27.1.1
if you have 28 SDK version change to 28.0.0-alpha1
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1

I am using Android Studio Canary 3.2 and looks like that.
So maybe is a bug of your Android Studio version.

I believe there is a problem with the Android Studio Preview which didn't load properly and needs to be checked. If you're using the latest Android Studio, try reopening-refreshing preview by clicking on Preview (in the right side of the app).
If this didn't solve the issue, double clicking on the Preview in the right side of the app when using code editor should show the preview or errors but i think it will be fixed by doing that since I've had the same issue and after reopening it, there were a force refresh
for the layout and it fixed the issue somehow.
