FAQ section for Learny template

Hi
I have the FAQ section on my index page which i have updated. A couple of things.
When you click on the + it expands but actually expands over the footer. How do i fix this please. Also the FAQ boxes in the bottom row do not expand. you click on the + and it doesn’t do anything.
Thanks
Sarah

Probably you have moved the element for outside of the main group and you are having a superposition of elements. Click element options and select "reveal in elements tree"and check.
