       <option ng-repeat="category in categories" ng-model="category_type">
          {{category.Category_Name}}
       </option>

<a ng-repeat="item in items | filter: // What should I put here?" href="#">

Answer 1

Assuming you have:

Catergory = {
id 
name
}

and

MeatType{
    id
    catergoryId
    name
    }

You can do something like

<a ng-repeat="item in meatTypes | filter: {categoryId : catergory_type.id}" href="#">

Answer 2

first of all you should use ng-option instead of ng-repeat like

<select ng-model="category_type" ng-options="category.Category_Name for category in categories"></select>

and use filter like

filter:{Category_Belonging_Id:category_type.Category_Id }

see demo here

尝试这个

<a ng-repeat="item in meatTypes | filter: {Category_Belonging_Id:category_type.Category_Id }"   href="#">
