i need a list that shows multiple items in one item
like List> list;

2

Found the answer

using System.Collections.Generic;
using UnityEngine;

public class listinsidelist : MonoBehaviour
{
	public List<pref> list;
}

[System.Serializable]//this line is important it will show your items in inspector
public class pref
{
	public string value1;
	public string value2;
	public string value3;
	public string value4;
}

Or if you need list inside a list
using System.Collections.Generic;
using UnityEngine;

public class listinsidelist : MonoBehaviour
{
	public List<pref> list;
}

[System.Serializable]
public class pref
{
	public List<object> ListInsideList;
}
