Cutting them at the preferred height will encourage the plant to grow more from the base, resulting in a bushier plant. However, it won't just stop growing where you cut it. You'll have to maintain the height by periodically trimming over-growth. As long as you leave the plant with a few leaves, and don't mangle it, cutting/trimming the plant is fine.
