I have a doubt.
I am using the child-theme of Renew with a lot of changes on the structure of the portfolio, for instance inside the portfolio item, I can work it using cornerstone.
Can I add, for example Integrity porfolio template, to the child-theme and keep the same structure changes?
Regretfully, this particular customization request is outside the scope of our support as this is not related to an issue with the theme and instead has to do with your customization of it. As such, you will need to investigate this particular issue on your own or seek help from a developer should you not feel comfortable making these changes yourself. If you have any further questions about the theme, we are more than happy to provide you with assistance on these inquiries.
