Create grids on a plane

Question

How can I create grids on a plane in Blender? Namely, a plan object is subdivided into multiple grid objects. I tried the following but did not work:

1. Create a plane
2. Select it in object mode
3. Tab to enter edit mode
4. Subdivide in into n components. In the viewport, I observe the plane is subdivided to the specified number of grids
5. Select all sub faces, and P Separate by Loose Parts
6. back to object mode. No new grid objects are either appearing in the viewport nor the outliner

Answer 1

I have been able to find the solution. It turned out I missed a step (edge split) prior to pressing P Separate > By Loose Parts. Naturally if don't split the edges there would not be any loose parts.

1. Create a plane
2. Select it in object mode
3. Tab to enter edit mode
4. Subdivide in into n components. In the viewport, I observe the plane is subdivided to the specified number of grids
5. In Edge mode, Split Edge. This fixed the problem
6. Select all sub faces, and P Separate > By Loose Parts

Back to object mode. No new grid objects are either appearing in the viewport nor the outliner.

Answer 2

In Object Mode, go to Add > Mesh > Grid
