How to configure first appearance of date filter in in range state?

If I declare filter type:date like this

  filter: dt_filter {
    type: date
    default_value: "from 2018/05/10  to  2018/05/12"
  }

it appears in this manner

but I want it in in range state
like this

I think I need to write right default value: “...”, but how?
