Modx pdoMenu how to output only the first level?

Question

MODX

The menu structure is as follows:

-Document without nesting
-Document without nesting
-Document with 1-level nesting
--nesting

-Document with 1-level nesting
--nesting

-Document with 1-level nesting
--nesting
--nesting

Naturally, the number of documents with nesting and without is unknown.

I need to display all the menu items of the first level, even those that do not have a nesting

pdoMenu use, but probably he can not do this,
&where = `{isFolder=1}` - not suitable, because then the output will only be carried out by parents, which have nesting, but which do not have its figs to you, and not the output.

Can thispdoResources or how to be in such a situation?

Answer 2
