Hi @Khai_Lunkim
I am still not clear on your question. Do you mean like below?

If so, the steps are simple
In Design studio:
1. Left navigation menu. Right-click the pages menu
2. Select > Move to other pages. Screenshot below for reference.

3. Once everything is moved then, move only the pages you want to "main navigation."
4. Then rearrange according to your need.
Alternative way
1. Click the "Navigation" header
2. Click "Edit Code"

3. Remove the Pages div block from the HTML.
------------
In Design Studio
1. Pres sync configuration and preview the website. And press "Ctrl+F5"
Hope it helps.
