Horizontal Rule

So I wanted to separate different sections of our form so I wanted a horizontal rule. Well I ended up creating a common interface with the following code and I added an input to allow me to choose between grey and blue colors. this interface utilizes the milestone field. Is there a better way? Here is the code:

with(
  if(
    or(
      isnull(
        ri!isblue
      ),
      ri!isblue
    ),
    a!milestoneField(
      steps: {
        "",
        ""
      },
      active: - 1
    ),
    a!milestoneField(
      steps: {
        "",
        ""
      }
    )
  )
)
