Hello all. I’m looking on how I can declare a public string in c# and it will offer a drop down list within the inspector. What can I google to look to see how it’s done?

A drop down list, do you mean a set of choice among a list?

You may want to use an enum then:

public enum State{
   walking,idle,attacking,eating,sleeping
}

public class AClass:MonoBehaviour{
   public State current;
}

This will show the variable with a list of possible choices

Here is a simpler way - Multiple Drop Down Selection

Simple 4 Steps

Step 1 : Make a new Script “EnumFlagsAttribute”

 using UnityEngine;
 using System.Collections;
 public class EnumFlagsAttribute : PropertyAttribute
  {
      public EnumFlagsAttribute() { }
  }

Step 2 : Make another Script “EnumFlagsAttributeDrawer”

using UnityEngine;
 using System.Collections;
 using System;
 using UnityEditor;
 
 [CustomPropertyDrawer(typeof(EnumFlagsAttribute))]
  public class EnumFlagsAttributeDrawer : PropertyDrawer
  {
      public override void OnGUI(Rect _position, SerializedProperty _property, GUIContent _label)
      {
          _property.intValue = EditorGUI.MaskField( _position, _label, _property.intValue, _property.enumNames );
      }
  }

Step 3: Enum Declaration

 [System.Flags]
     public enum FurnitureType
     {
         None , SofaPrefab , Curtains , Table , Chairs 
         }
 
  [EnumFlagsAttribute]
     public  FurnitureType   enumType;

Step 4: Getting Selected Elements

List<int> ReturnSelectedElements()
     {
 
         List<int> selectedElements = new List<int>();
         for (int i = 0; i < System.Enum.GetValues(typeof(FurnitureType)).Length; i++)
         {
             int layer = 1 << i;
             if (((int) enumType & layer) != 0)
             {
                 selectedElements.Add(i);
             }
         }
 
         return selectedElements;
 
     }

There is another short trick for this

  public enum State{
        walking,idle,attacking,eating,sleeping
     }
     
     public class AClass:MonoBehaviour{
     public static string[] names = {"walking","idle","attacking","eating","sleeping"}
     public State current;
     public string getCurrentState(){
          return names[(int)current];
     }
    
     }
