I am not sure if this is possible !

I have two files say **main.php** and **submenu.php**
In **main.php** i have the following mainMenu
![enter image description here](https://i.stack.imgur.com/TAkvB.jpg)

and in another file called **submenu.php** i have a list say

```
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
</ul>

```

If i click on **Pricelist** in main menu i want to display the content of the submenu as a list under PriceList as

The simple solution may be including the list view in menu.php itself, But that's not the situation 

Thank you.
