How to reduce drawcall, which actually not rendered?

hi dev team, i’m confused, why hidden nodes considering as Drawcalls, how it works?

in black area there is a Listview with items, and it’s considering as 300 drawcalls (CC 2.4.6)
WHY?

there is another picture, 50 items in list with same sprites which in autoatlas but still more 100 drawcalls, where is Batching?

thanks

Remove Label and see the magic.
Label will cut auto-batching.

This needs to manage the hierarchical relationship of the nodes. If images and labels are mixed, it will break the merge batch.
For example

picture
     label   
picture
    label

change to

picture 
picture
    label
    label
