Displaying items grouped by "custom post type categories"

I have a custom post type called Item Category that simply contains the names of all my item categories (saved as posts) such as

• Vehicles
• Rental
• Camping

There are no ACF-related fields within this custom post type.

I have another custom post type called Items. Here I can create items and for each individual item, I can select multiple item categories (Vehicles, Rentals, Camping) based on the ACF “Relationship” field that pulls the categories from the Item Category CPT.

On the frontend of the website, I am wanting to display the items grouped by categories, something like this:

Category: Vehicles

• Item: Car
• Item: Truck

Category: Rental

• Item: Car
• Item: Tent

Category: Camping

• Item: Tent

When I run a query like this:

foreach ($posts as $key => $val):
   echo $val->post_title; // Displays item name
   print_r(get_field('category', $val->ID)); // Displays array of categories
}

, it simply displays items and it’s related categories.

How do I resolve this?
