Trying to make something happen in the Editor and not runtime, how do you do this/is it possible?

I want to make a script that I attach to gameobjects in a scene. I want the these objects to have one or more attributes. What I am trying to do is when I attach the script to the gameobject it will have checkboxes for various attributes, like if it is a food item you will check that box, if it is water or health you check one of those boxes. The problem comes because I want the script to, if you check one of those attributes, create or expose a variable to tell it how much to give of whatever the attribute is. For example, if I check that health it true, I want a new window to appear with a float variable where I can enter the amount of health for that object. I want to do this to make it fast and easy to make and change a large number of these through the editor without having to go into the code to do it. Here is the script idea-

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class Attributes : MonoBehaviour
 {
     public static float health;  //this will go in my main health script, not here
 
     public bool isHealth;
 
     /*  if (isHealth == true)      // I want to create a new public variable newHealth in the editor, not at runtime
           {
               public float newHealth;
           }*/
 
     public bool isWater;
 
     public bool isFood;
 
     public bool isCraftable;
 
     
 
 
 
 
 
 
     // Use this for initialization
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
 
 
 
 
 
     }
 
     public void Consume()
     {
        health = health + newHealth;   //his is the second big problem. if I use a variable before it is 

created, it will throw an error of course, any way around that? } }
