How to create own BranchActionGroupPopup?

Hi, This one is a little bit hard to explain and maybe much harder to solve. I have created my own GitBranchPopup-Menu which extends from MyDvcsBranchPopup. Why do i need this?: I need a branch-selector, but in my case i dont need multiple actions (Checkout, New branch from selected, ... Push, Rename, ect)

i need a flat menu instead. i was able to create this. but unfortunately if you collapse the list tho only show favs

it is not longer possible to search over the collapsed items (with visible items it works):

If you show all items in the list it works with all list items again:

I think the Problem is

HideableActionGroup

https://bitbucket.org/comodmw/git-scope/src/b4e3118c332e5ad4b8b7cf0f5a0e80fc10f42cf1/src/main/java/implementation/targetBranchWidget/MyBranchActionGroupPopup.java#lines-320

which needs to be implemented as a *group* action. i cannot use this as is, because i pass my own

myBranchAction

which is not compatible, so i need to write my own (this whole thing ended with 7 classes :-) https://bitbucket.org/comodmw/git-scope/src/TargetBranchPopup/src/main/java/implementation/targetBranchWidget/ )

who can help me to finish this method?

    private HideableActionGroup(@NotNull MyBranchAction myBranchAction, @NotNull MoreAction moreAction) {
      super(new ActionGroup() {
        @NotNull
        @Override
        public AnAction[] getChildren(@Nullable AnActionEvent e) {
//          return new AnAction[]{myBranchAction};
          if (!moreAction.isExpanded()) {
//            myBranchAction
//            return new AnAction[]{myBranchAction};
//            return new AnAction[]{new EmptyAction(myBranchAction)};
            // @todo Searchable Actions
            return new AnAction[]{new EmptyAction()};
          } else {
            return new AnAction[]{myBranchAction};
          }
        }
      });
      myMoreAction = moreAction;
    }

Thanks!
