jquery dropdown and text boxes don't work on ios chrome browser

I have a very basic search page with dropdowns and text boxes.
The snippet looks like following
<div class="container" style="width: 100%;">
<div class="row">
<div class="input-group col-sm-4 col-md-4" style="float: left; margin-bottom: 10px; max-width:0px;">
<span class="input-group-addon" id="basic-addon2">Business Name</span>
#Html.LabelFor(m => m.Parameters.BusinessName, new { style = "display: none;" })
#Html.TextBoxFor(m => m.Parameters.BusinessName, new { #maxlength = 50, #class = "form-control", #placeholder = "Enter a business name", #aria_describedby = "basic-addon2", #style = "width:350px;" })
</div>
<div class="input-group col-sm-4 col-md-4" style="float: left; margin-bottom: 10px; max-width:0px;">
#Html.LabelFor(m => m.Parameters.BusinessNameSearchType, new { style = "display: none;" }) #Html.DropDownListFor(m => m.Parameters.BusinessNameSearchType, searchtypes, new { #class = "form-control", #style = "width:150px;" })
</div>
</div>
</div>
And on the page this snippet looks like following.
I use bootstrap 3.3.5 and jQuery 2.1.4.
It works perfectly fine on desktop, android tablet, and android phone, when I use Chrome as a browser.
However, both textbox and dropdown break completely (break as becoming completely unusable) when I try viewing it on the newer versions of iPhone ios Chrome browser.
Interestingly enough, when I tried to emulate it in Chrome as the iPhone X, it worked fine as well.
I am completely new to the whole ios topic. Doing some basic research led me to believe that older versions of bootstrap/jquery might be the issue.
Trying to update to bootstrap 4, which also leads to updating jquery to 3.0.0, completely breaks the whole application, so I had to revert it back.
Before I dive too deep into fighting the whole bootstrap/jquery thing, can anyone please provide me any useful pointers to why ios is so picky? I want to get at least the basic understanding of what the problem is before I start digging into possible solutions.

I have added two example with help of (Bootstrap-4) as your posted instruction.1st - Break textbox and dropdown on mobile.2nd - Not break textbox and dropdown on both Desktop & Mobile.
You can check below snippet.

Form submit not working on chrome in Samsung A8 (android)

I am using a simple form to send an email but on my device the click is not firing anything.
Here is my code:
<form class="form-inline" action="mailto:user#gmail.com?subject=oggetto" method="post" enctype="text/plain">
<div class="col-md-4 col-sm-4">
<div class="form-group">
<label for="name" class="sr-only">Nome e Cognome</label>
<input type="text" name="name" class="form-control" id="name" placeholder="Nome e Cognome">
</div>
</div>
<div class="col-md-4 col-sm-4">
<div class="form-group">
<label for="bambini" class="sr-only">Numero bambini</label>
<input type="name" name="bambini" class="form-control" id="numBambini" placeholder="Numero di bambini">
</div>
</div>
<div class="col-md-4 col-sm-4">
<input type="submit" class="btn btn-default btn-block">
</input>
</div>
</form>
I tried also with
the tag button type="submit"
with no luck.
My code is working fine on Chrome desktop but on my samsung device works only with Samsung Internet and not with Chrome (I also got the same with a samsung p20).
Any idea on how to fix it?
Thanks

laravel 5.4 chrome for android not showing validation errors

I have a website working perfectly on desktop, however, google chrome is not showing validation error messages or flash info.
I tried other navigators like html source code viewer: worked perfectly
on chrome for desktop, everything is ok
when I serve my project from my computer and access it throgh wifi, it works perfectly
My server is running nginx on linux debian
The problem is, this only happens on my signin/signup page, other pages are showing errors and flash messages perfectly even on chrome for android
here is my view:
<h3>Welcome back</h3>
<div class="row">
<div class="col-lg-6">
<form class="form-vertical" role="form" method="post" action="{{ route('auth.signin') }}">
<div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}">
<label for="email" class="control-label" id="email">Email</label>
<input type="text" name="email" class="form-control" id="email">
#if ($errors->has('email'))
<span class="help-block">{{ $errors->first('email') }}</span>
#endif
</div>
<div class="form-group{{ $errors->has('password') ? ' has- error' : '' }}">
<label for="password" class="control- label">Password</label>
<input type="password" name="password" class="form- control" id="password">
#if ($errors->has('password'))
<span class="help-block">{{ $errors- >first('password') }}</span>
#endif
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="remember"> Remember me
</label>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary">Sign in</button>
<a style="padding-left: 10px;" href="{{ route('auth.forgot') }}">Frogot your password?</a>
</div>
<input type="hidden" name="_token" value="{{ Session::token() }}">
</form>
</div>
</div>
<script>
(please don't mind the spaces in the code, I don't have these in my page)
inside my controller, I have this:
$this->validate($request, [
'email' => 'required',
'password' => 'required',
]);
and I show flash messages this way:
return redirect()->back()->with('info', 'Incorrect sign in information.');
can you please help me out? this is really weird and frustrating
thank you

Haser!
I have the same problem on the test server, but the production is ok.
Having studied all the circumstances, I am inclined to believe that in my case the problem lies in the absence of https on the test server.
My logic is this: mobile chrome sees the password entry field and sees that there is no certificate. These two circumstances come to non-standard behavior. Indirectly, I managed to confirm my theory by studying the password change page, there is the same situation with the absence of errors.
This behavior is observed only in mobile chrome on android!

Phonegap: How to show configuration screen only once

I have started work on Phonegap and it is very hard for Native App developer to go for Hybrid.
Just want to know that how I can show configuration screen only once in Phonegap. Below is the screenshot. I just want to show it only when user runs an app first time, and not again and again whenever user launches an app and saves IP address.
The problem here is that, whenever I press back button of device, this screen gets display.
Here is my HTML:
<body>
<div data-role="page" id="pageConfig"> // This Div needs to show only first time
<div class="ui-content" data-role="main">
<h3>Configurations</h3>
<label for="ipText">IP Address:</label>
<input type="url" id="ipText" name="ipText" />
Save
</div>
</div>
<div data-role="page" id="pgLgn">
<div data-role="main" class="ui-content">
<form id="form1" class="validate">
<div class="ui-field-contain">
<label for="usrNme">Username:</label>
<input type="text" name="usrNme" id="usrNme" placeholder="Username" data-clear-btn="true" data-theme="d" class="required" />
</div>
<div class="ui-field-contain">
<label for="pswrd">Password:</label>
<input type="password" name="pswrd" id="pswrd" placeholder="Password" data-clear-btn="true" data-theme="d" class="required" />
</div>
<div class="ui-field-contain">
<input type="checkbox" id="chbx-0" class="custom" data-inline="true" />
<label for="chbx-0">Remember me</label>
</div>
<input type="submit" data-inline="true" value="Login" id="btnLogin" data-shadow="false" data-theme="a" onclick="OnLoginClick()"/>
<input type="reset" data-inline="true" value="Reset" data-shadow="false" />
</form>
</div>
</div>
</body>
What Cordova Plugin I need?
NOTE: I am using Jquery Mobile and Cordova SQLite Plugin for data storage. And my app is Single Page Architecture.
Thanks in Advance!
Please let me know if not clear.

You have to write this line in device ready function.
document.addEventListener("backbutton",onBackKeyDown,false);
function onBackKeyDown(){
if($.mobile.activePage.attr("id") == "pgLgn"){
navigator.app.exitApp();
}
else{
navigator.app.backHistory();
}
}
Use localStorage. Save a simple string with key and check whether there is a particular value against key or not in deviceready function.

bootstrap 3.0 on android phonegap

is there any known issue of bootstrap 3.0 (the latest one) on android phonegap. I am able to see the buttons nicely on firefox (and on same resolution as on phone) but when the binary is installed on the phone the buttons do not render....
is this a known issue ?
Following is my simple template:
<div id="mcontent">
<div id="swrapper">
<div id="islider">
<div class="btn-group btn-group-justified">
<a class="btn btn-default" href="#">Mrs</a>
<a class="btn btn-default" href="#">Ms.</a>
<a class="btn btn-default" href="#">Mr.</a>
</div>
<form>
<input type="text" name="firstname" placeholder="Firstname">
<input type="text" name="lastname" placeholder="Last Name">
<p><input type="text" name="email" placeholder="Email"></p>
<p>Must be at least 8 characters long</p>
<input type="password" placeholder="Password">
<input type="password" placeholder="Password repeat">
<p><button type="submit" class="btn btn-primary btn-large btn- block">Submit</button></p>
<p><span id="dclaimer">By registering you confirm that you accept our Terms of Use and Privacy Policy</span></p>
</form>
</div>
</div>
</div>

I know this is an old post but I have had the same issue. I believe this is down to jquery mobile. As when i removed it, it worked
Removing just the css of jquery mobile seems to keep jquery mobile functionality and allow bs to work
