Show Hide QueryType options

Hi,

I want to hide options from Query Type Dropdown, If I select part from grid then only (Current and Release should be visible).

So for that I tried this way: 

Code in ItemsGrid.html file, I call a function inside initMenu() function.

below is my code: 

function dr_showHideQueryType(itemTypeName){

 Current = getChoiceItemName(0);
 Latest = getChoiceItemName(1);
 Released = getChoiceItemName(2);
 Effective = getChoiceItemName(3);

 var opts = [];
 opts[Current] = false;
 opts[Released] = false;
 opts[Latest] = false;
 opts[Effective] = false;

 if(itemTypeName === "Part"){
  opts[Current] = true;
  opts[Released] = true;
 }
 else{
  opts[Current] = true;
  opts[Released] = true;
  opts[Latest] = true;
  opts[Effective] = true;
}
  for (opt in opts) {
     if (!opts[opt]) {
         removeChoiceItem(opt);
     }
  }
}
function getChoiceItemName(id) {
  var tbi = searchbar.getActiveToolbar().getItem("query_type");
  var tbi_id = tbi.getItem(id);
  return tbi_id;
}
function removeChoiceItem(name) {
  if (name == undefined) {
  return;
}
var query_type_tbi = searchbar.getActiveToolbar().getItem("query_type");
try {
  query_type_tbi.remove(name);
}
catch (e) { }
}

But not able to achieve the expected behaviour, is anything i'm missing.

Regards,

Maddy.
