Android not opening dropdown menu from select element

Android not opening dropdown menu from select element

I'm developing an mobile application using phonegap(2.9.0) and right now
i'm struggling with few android bugs related to select elements.
In advance, sorry for the poor paint "wireframes" haha

There's a form inside the relative positioned container. The select
elements were not opening the dropdown menu. After some research, this one
was solved setting the meta tag viewport with "user-scalable = yes".
Tested on Android 2.3.6: Samsung Galaxy Ace(GT-S5830C) and Motorola Defy
Mini(XT-320); Android 4.1.2: Motorola Razr D3(XT920). However, it's not
working on android 4.0.4: Samsung Galaxy S Duos(GT-S7562).

At this screen, there's a form inside the container inside the absolute
positioned div. The select elements are not working even with the meta tag
workaround. And this is driving me completely insane. At first, i thought
that the problem was the fact that i'm styling the select elements. After
removing EVERY style, it didn't work. The most close to a solution i've
got was doing it programmatically with JS, however, despite the fact that
only thinking about doing it make me want to cry, didn't work as expected,
because the dropdown menus sometimes opened, sometimes not. Sincerely, i
have no idea about why the hell is this happening. Tested on the same
devices as the screen above.
Can anyone please help me?? Thanks in advance
