How to display the “Add a review frame” into a button

Hello,

Do you know if it is possible to click on a button to show/hide the “Add a review” frame ?
Here is a picture of the frame I want to be embedded into a button.

The idea behind this is I want to show the reviews when the user scroll a page product, so I display all tabs vertically.
But the “Add a review” frame is taking much space so I would like the frame to be hide by default and only show when the user click on a button.

Thanks
