Not show menu when is right click on items that appears above container contextmenu.

[cplaiu]

I am creating a context menu container where user right click and can add folders. All this folders appears above this container and I'm trying to prevent display contextmenu on it.

I have tried to prevent diplay menu using this code:

$(document).on("contextmenu", ".folder-box", function(e){
  e.preventDefault();
  $('.context-block').contextMenu(false);
});

$(document).on("contextmenu", ".context-block", function(e){
  e.preventDefault();
  $('.context-block').contextMenu(true);
});

but the context menu is still showing when right clicking.
