Hi all,
I'm having a bit of trouble formatting my table of contents. The issue is with the headings.

As you can see from the image below my contents layout is something like;


Chapter 1
1. Introduction

I'm trying to get it on the same line so it looks like;

Chapter 1 - Introduction



The problem is related to the image below. I want to keep the multilevel at the chapter title but if I remove it the subheadings change. Is there any way of keeping the subheadings to match the chapter number but make the number invisible? Pretty difficult to explain so I've made an example.

Original:

Chapter 1
1. Introduction -------- Here is the first heading - trying to remove the number without messing up the formatting
1.1 History
1.2 Applications

Chapter 2
2. Theory ----------- Is there a way of hiding this number?
2.1 Background
2.2 Information

If I remove the heading number field, then the subheadings carry on from the first chapter so they go 1.3, 1.4 and so on even though I'm in a new Chapter. Is there any way of getting them to go to 2.1, 2.2 without putting the Chapter heading in?



Tried to explain it as best as I can, any help will be much appreciated.

Regards
