Widget Menu - MenuData

Hi, I have a menu configured with the MenuData property but whenever I change the option it opens the mashup in a new window but I need it to replace the current one, what configuration should I put in the service? At the moment I have this

result.AddRow({
linkDestination: 'MenuTest',
isDefault: true,
parentMenuId: 'topMenu',
imageURL: '',
linkTarget: '', // (Popup, Mashup, 'Replace')
description: '',
menuId: 'idOverview',
linkType: 'Mashup',
title: 'Over'
});
