# how to make cells independent with each other in notebook

If we open DocumentationCenter and then run code, we will find that the Cells are independent from each other.

For example:

• a or b in third Cell is independent from the one in the first or second Cell.

I think maybe it is local cell?

If I want to achieve this behaviour in my notebook, how to do this?

Thanks.

Not each Cell but each CellGroup has separate context. If you create new cell you will get In[2]:
nb = Select[Notebooks[], "Help" === ("DocumentType" /. NotebookInformation[#]) &][[1]]

{{CellContext -> CellGroup}, <<18>>, {CellContext -> CellGroup}}

So it is an Option that you can fix, e.g. via menu:
