InDesign Tips: Master Page Always On Top

In the past, I'm quite confused on how to keep the master page on the top of other layout in InDesign. Everytime I put objects on top of the master page, the object on the master page (page number, header, footer, etc.) is covered by the content. But actually, I found out that the solution is very simple and using a system that Adobe usually use: LAYER!

Here's how:
1. Open the "Page" panel. Go to Master Page.
2. Then go to "Layers" panel.
3. Then add a new layer by clicking the "Create New Layer" icon on the corner below of the "Layers" panel.
4. Now simply create the basic layout (page numbers, header, footer, etc.) you want on the Master Page
5. After you've done, just get out of the Master Page by clicking the other page on the "Pages" panel.
6. DONE :)
