There is no problem whatsoever to use "dtml-if" inside "dtml-in".

"dtml-in" works with sequences.

In your example, however, you give it an integer ("level").
It will not be happy with this.

You may try:

<dtml-in PARENTS>
  <dtml-let PARENT="_.getitem('sequence-item')">
    <dtml-if "PARENT.hasProperty....>
    ....
