XF 2.1 Showing Ad on Resources page

[applelappalala]

The default Advertising category doesn't have a widget to show Advertise on resources.

1. I want to display Ads on Resources sidebar, how can we do that?
2. And also, I tried to display Ads on Fourm sidebar above, but it doesn't display.
3. How can we make a Ad as sticky in sidebar.

I don't know coding so, please answer me clearly.
Thanks.
