is it possible to showing a category-view of specific ids in a item-view?

hello

I need to make a quite complex structure

I have Partent-Items (Type 1) with many fields
There gonna be Child-Items (Type-2), which I can "Connect" with one Parent-Item.
So one Parent-Item can have many Child-Items; a Child-Item only can have one Parent...

I use the Field Relation in the Child-Items (Type 2); and the Field Relation-Reverse in the Parent-Item (Type 1)

Because the site is multilingual and the view of the Relation-Reverse Field is quite complex; it would be great if I can use a category view for the Relation-Reverse
I do get an array of the id's of the Child-Items in the Parent-Item - but how can i load them in a flexi-template. is that somehow possible?

for any tipp I'm very thankful

I first wanted to use the "child-items" in the parent item with "field in a group" - but i use the J2Store-Field; and that one i can't use in a group...

we didn't do this field ask dev for group value support

I had a look at the field - it goes to the item id... so long way to do a workaround...

i guess i found now a solution with the flexicontent universal content module
