Subject of the issue

staticGrid disables one column mode.

Your environment

• gridstack.js version 1.1.0
• Chrome

Steps to reproduce

One column mode is disabled here:
https://jsfiddle.net/ur81se2n/2/
...but should be enabled?

Disable staticGrid like this:

...to enable oneColumnMode.

How do I enable staticGrid AND oneColumnMode?
(it worked in gridstack 0.4.0)
