jquery mobile, error with select menu in Android with Chrome version 50

I have updated my Chrome browser to last version and I have the following problem:
When I select an option of a select menu it does not appear selected, I repeat the process of the selection and then it is selected OK. If I try to select other option it happens the same, first time bad, second time OK. It is happening since I have update to version 50 of Chrome, with previous version 49 it worked OK.
I am using a Huawei Y5 with Android 5.1.1, it happens the same with a Nexus with Android 6.
The version of jquery mobile that I have is 1.4.5
It seems only happens with Chrome version 50 in Android, in desktop works fine. In the browser that Huawei has, works OK.
To test this problem is easy, just go to the demo of select menu of jquery mobile:
http://demos.jquerymobile.com/1.4.5/selectmenu/
One important thing, in previous versions of jquery mobile works fine, examples:
http://demos.jquerymobile.com/1.3.2/widgets/selects/
Is there any way to resolve this problem? Any help would be appreciated.
Thanks in advance,
Félix.

I have to question the logic behind JQuery Mobile hiding the toolbars on select element focus by default. The native browser select elements overlay the page in their various special ways, and even the non-native select popup (which you get when specify the data attribute data-native-menu="false" in html or nativeMenu: false in the selectmenu options) is absolutely positioned as a dialog. This means that the toolbars really do not intrude on the real-estate given to the selectmenu options as they'll always overlay everything including the toolbars. To me, this makes the code from line 12664 - 12692 commented as: this hides the toolbars on a keyboard pop to give more screen room rather unnecessary for select elements.
Workaround/solution: thankfully jQuery-Mobile does nicely allow you to override this setting in your header/footer with the data-attribute data-hide-during-focus - simply set this to:
data-hide-during-focus="input, textarea"
and it won't try to hide the toolbars anymore when a select element gets focus.
i.e. simply change your header from this:
<div data-role="header" data-position="fixed" data-tap-toggle="false">
Header
</div><!-- /header -->
to:
<div data-role="header" data-position="fixed" data-tap-toggle="false" data-hide-during-focus="input, textarea">
Header
</div><!-- /header -->
... and the same goes for the footer.

Ratchet Framework scrolling in Android 2.2

Im using Ratchet Framework for andriod app development.
I have some scrolling problems in some android phones and also in bluestack.
when scrolled, a toomany blank spaces occurs and it affects the smooth scrolling. also affects the forms in the page. attached the image related
scrolling on some other devices is good , No extra space.

1) make sure you are using the meta tags provided by ratchet.
2) make sure you are inserting the bar-tab navigation at the top right after the body
From the ratchet getting started guide:
1. Fixed bars come first
All fixed bars (.bar) should always be the first thing in the of the page. This is really important!
2. Everything else goes in .content
Anything that's not a .bar should be put in a div with the class .content. Put this div after the bars in the tag. The .content div is what actually scrolls in a Ratchet prototype.
3. Don't forget your meta tags
They're included in the template.html page included in the download, but make sure they stay in the page. They are important to Ratchet working just right.
If that doesn't help post some code and let us take a look at it

Android Phonegap Scroll not work

i developed an android app by using html5 and phonegap (cordova 2.7.0); it's an application for image search, use the google API.
Returns a list of images that start with a tap.
It works perfectly on almost all devices, but on small screens with Android 2.3.x, scrolling (or click on image) does not work.
Any suggestions?
Thanks in advance.

You have run into an android bug. Overflowing DIVs inside BODY tag wont allow you to scroll. Same bug was there in iPhone (iOS < 5), but there atleast you could use two fingers and scroll.
However there are workarounds for it. You can use third party libraries such as iScroll, touchScroll ...
iScroll will disable your inputs for the div which you have applied scroll to. If its a simple paragraph use iScroll.

While 2-Stroker's answer is the correct one here is a quick and dirty solution, add a few <br> tags at the end. Worked for me ;)

If you don't want to go through the trouble of adding iScroll you can also use:
// Workaround for problematic scrolling behaviour on Android
// we can't fix this in css directly as it breaks iOS and the
// platform selector in css is unreliable
if ( device.platform === 'Android' ) {
$('.ui-mobile, .ui-mobile .ui-page, .ui-mobile [data-role="page"], .ui-mobile [data-role="dialog"], .ui-page, .ui-mobile .ui-page-active ').css("position", "initial");
}

Select inputs not responding in Android mobile browser

I have a simple form with one select input type that works fine on all desktop browsers as well as mobile Safari. However, on both my Android devices (Samsung Droid and Prevail), the select input will not respond. I'm expecting it to spawn a picker. Has anyone had a similar experience? Any advice? Thanks.

I had a similar problem and solved it with the following meta tag:
<meta name="viewport" content="initial-scale=1.0; maximum-scale=1.0; user-scalable=yes;" />
And I noticed that, in my case, when a parent element was hidden (and displayed again) the select element behaves 'disabled'. There is a bug in android =< 2.2 when you change the style, the dom is not re-rendered. You can force to re-render the dom by adding (or changing) a 'fake' attribute to force dom re-rendering. e.g:
myPreviousHiddenEl.setAttribute('forceRePaint','yes');

I was having this problem and I think it had something to do with overlapping like you said. To fix it I added the following CSS to the tag like this:
<select style="position:relative">
That got the job done. :)

Just encountered the same issue.
I'm using Bootstrap and one of the <div>'s in the lower section had col-sm-12, but no rule for xs. This was causing it to invisibly cover up all of the above form input elements in mobile. Switching col-sm-12 to col-xs-12 fixed the issue.

HTML <select> control disabled in Android WebView (in emulator)

I have a very simple Android app that's just a WebView. Everything works fine (complex Javascript etc.). However, all of the HTML select controls seem to be disabled. They display with default values, but nothing happens when I click on them, and they don't get the orange highlight when I arrow through the controls.
Other inputs (text, radios, submit) work fine, so I don't think it's a focus issue.
Configuration:
Eclipse IDE
SDK Version 8 (2.2)
Testing in the Emulator

I had the same problem. My problem was fixed by changing overflow:hidden to overflow:visible on a containing element.

I had the same problem.
In my case I had elements on the page that had the style position:fixed;
Although the bounding boxes of the select element and the fixed positioned elements did NOT overlap, I wasn't able to open the select dialog.
By removing a couple of fixed positioned elements I got it to work. Seems to be a bug in webview.

Same Problem, fixed it by setting position:relative on the li's containing the select fields

2 years after the fact, but in case someone pulls this up again:
If it's android 2.3, put in every empty child element of a fixed position parent. I found that this fixed the problem for me.
