Edit Shopware 5 Template Left Menu

In the standard responsive shopware 5 Theme there is a menu on the left side. We want the menu to hide certain categories on the parent level. See picture attached. Today: When user is currently in category 2.2 or 2.2.3 showing product listing it also shows same level parent categories. Like this: Category 2.1 Category 2.2 -Category 2.2.1 -Category 2.2.2 -Category 2.2.3 Category 2.3 Category 2.4 We want to hide the same level categories, when within a certain category. Goal: When user is currently in category 2.2 or 2.2.3 showing product listing, we only want to show its sub categories and NOT the parents. Like this: -Category 2.2.1 -Category 2.2.2 -Category 2.2.3 This must also work, if the user is in 2.2 (only display level below) or in 2.2.1 or 2.2.2 (only display same level) Requirements Behavior must only show in certain cetegories, not in any other (id should be checked in if statement) Must work for Shopware 5.1.5 and 5.3.4. No access to our systems. You have to develop and test on your on system. We are using the standard shopware 5 responsive theme Changes must be written into template file, so that future shop updates still work
