As you can see I have a DraggableFlatList which has list of data with structure like categories and categories has list of items. List of item are also in DraggableFlatList.
When I click on category name list expand. We can drag and drop both by category and items inside a category.
Now the issue is when I expand a category I can drag and drop the item but not able to scroll the list. For more understanding a video of problem is attached.
Also, I am passing 19 item but DraggableFlatList show only 10 some times and some time all.
Any help appreciated.

@matanrokach-honeybook I’ve fixed a problem with scrolling like this:
Add a activationDistance const to check state.
const [activationDistance, setActivationDistance] = useState(100);Add a scrollEnabled prop for parent scrollview.
<ScrollView style={{flex: 1}} scrollEnabled={activationDistance !== 0}>Set activeDistance prop
setActivationDistance hook I’ve used on onDragEnd function and long-press element
For me, it is working fine.
i have the same issue with Horizontal DraggleFlatlist inside DraggleFlatlist
