Is there a way to use different sidebars on pages? For example on a page to use the “page sidbar” and on another page to use “portofolio sidebar” or “blog sidebar”. If yes can you plesase assist me on how to set the side bar that a page uses?
That is not possible.
But..you can add as much custom sidebars as you want. Go to General Options > Custom Sidebar (screenshot).
Then add content to them from Appearances > Widgets.
Let me know.
