How to change text in dropdown menu in C# during runtime

Questions & Answers

I want to have a drop down menu that can change the text in each field during runtime (using an enum). I have an enum set up, but I can’t figure out or find any way to change the text of the options from script.

You need to import:

using UnityEngine.UI;

and then use this code:

public Dropdown dropdown;

void Start () {
    dropdown.options.Clear ();
    dropdown.options.Add (new Dropdown.OptionData() {text = "your stuff"});

}

If you want to change only a single Item:

Dropdown thisDD;        
void Start ()
{
      thisDD = GetComponent<Dropdown>();	
}
		
void changeDDItemText(string newText,int index)
{
    if (index < thisDD.options.Count)
    {
        Dropdown.OptionData newItem = new Dropdown.OptionData(newText);
        thisDD.options.RemoveAt(index);
        thisDD.options.Insert(index, newItem);
    }
}

If you wanna change the whole dropdown menue:

 void newDD(List<string> newDDList)
 {
      thisDD.options.Clear();
      foreach (string option in newDDList)
       {
           thisDD.options.Add(new Dropdown.OptionData(option));
       }
 }
