Unity / How to Hide "Editor Script" in the Inspector?

I want to hide the "editor Script" in the Unity Inspector, so it doesnt show up with all the other components (transform/other scripts etc.) It works with every other "normal" component like this:

component.hideFlags = HideFlags.HideInInspector;

but when it comes to the Editor Script- it just doesnt hide.

EDIT: My Custom Editor Script:

using UnityEngine;
using System.Collections;
using UnityEditor;

[ExecuteInEditMode]
[CustomEditor(typeof(DetailCamContScript))]


public class CamEditor : Editor
{

    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();

        DetailCamContScript myScript = (DetailCamContScript)target;
        if (GUILayout.Button("Set Camera Active"))
        {

            myScript.setCamActive();

        }


    }

}

EDIT: Problem solved.

the problem was: The editor-script was attached to a Gameobject. It doesnt needs to be attached.
