Particle Screen Alignment

I am trying to create a ripple effect on water with particles but they are always aligning toward the camera. What do I need to change in “screen alignment” to make it orient on the XZ plane?

Add an Orientation -> Lock Axis block to the particle. Then pick the right orientation within the properties of that newly added block. So it is not actually Screen Alignment you change.

I was trying that but maybe I was missing something because it works now though… thanks!
