如何显示相同列的结果但在laravel中具有不同的值

Here i'm returning data from my database which have a title_heading column and it has a title column.

 id     title_heading    title

 1     HTML Tutorial     Home
 2     HTML Tutorial     Overview
 3     HTML References   Tags 
 4     HTML References   Events

but now i wanted to show the results like this in my view:

**HTML Tutorial**
   Home
   Overview

**HTML References** 
   Tags
   Events

If anyone have any idea please let me know... Thank You!

i have two idea on this.. first normalize that table into two table..

heading : [id,name] subTitle : [id, name, heading_id]

then you make oneToMany Relationship in laravel

second you can use nested loop it and push it into array..
