$(document).ready(function () {
  $("#block_1").change((e) => {
    console.log("block_1 select ", e.target.value);

    $("#children_1")
      // .find("[value!='" + e.target.value + "']")
      .find("option")
      .removeAttr("selected");
    $("#children_1")
      .find("[value='" + e.target.value + "']")
      .attr("selected", true);
  });
});
