Heelo i have a question. I have a fetch function that that trigers oneditprepare and that gives me dropdown of 3 objects. next to it i have a button which works as "refresh server". Basically on btn click i call the fetch function again .The problem i have is that when i click the button it gives back same 3 objects below other objects. I want when i click on the btn to not have same objects shown

```auto
  for (let i = 0; i < options.length; i++) {
              let value = options[i].v;
              let text = options[i].t;
              $("#node-input-options").append(
                $("<option></option>").attr("value", value).text(text) //For every element in the select tag append appropriate value and text ( <option value="#">#</option> )
              );
            }

```

This fills the dropdown

```auto
  const btnrefreshServer = $(".refreshserverItems");
      btnrefreshServer.on("click", (evn) => {
        let select = document.getElementById("node-input-options");
        let length = select.options.length;
        for (let i = length - 1; i >= 0; i--) {
          select.options[i] = null;
        }
        setTimeout(fetchUrl, 1000);

```

I tried like that but it doesnt work
