@xMarston Sorry for late reply.
I was really busy these days.
So I confirmed what the problem. The ionic places the sidebar under the contents div tag.

I’m sorry, this is out of the scope I expected.
This problem occurs by phonegap-googlemaps-plugin, because the map plugin changes the background color to transparent.
Because the map view places under the browser, so the browser must be transparent.

Is there any way to place the sidebar OVER the contents page?
(Sorry I’m not familiar with ionic framework)
Edit: @Melina comes up with another solution.
He/She changes the visibility of the CSS. That’s one of the right way. Please try it, @xMarston.
