Hi All,
I am facing a strange problem with Combo boxes.
I have created an web application with the help of ExtJS, which run on iPhone device.
When i am testing my application page on iphone, vertical scroll bar is not coming on combobox list.
Now I have a combobox (dropdown) in js file.
code is :
xtype : 'combo',
fieldLabel: 'Birth Date',
store: new Ext.data.SimpleStore({
fields: ['birthDate', 'bdate'],
data : [
["01", "01"],["02", "02"],["03", "03"],["04", "04"],["05", "05"],["06", "06"],["07", "07"],["08", "08"],["09", "09"],["10", "10"],
["11", "11"],["12", "12"],["13", "13"],["14", "14"],["15", "15"],["16", "16"],["17", "17"],["18", "18"],["19", "19"],["20", "20"],
["21", "21"],["22", "22"],["23", "23"],["24", "24"],["25", "25"],["26", "26"],["27", "27"],["28", "28"],["29", "29"],["30", "30"]
valueField: 'birthDate',
displayField: 'bdate',
typeAhead: true,
mode: 'local',
triggerAction: 'all',
emptyText:'Select Day',

now combobox list is showing 30 days. but vertical scroll bar is not coming on combobox list.
Please see the screenshots attached.25473

As you replied IPhone never shows scrollbar for nested divs.
if I have 30 days in combobox list as code i use in previous post, then if user want to select 28th day from combobox then how the user will go on 28th days without scrolling . how this is possible to scroll bar up and down in combobox.
So Please give me idea how to fix this problem.

You scroll these areas with 2 finger swipes... Or you might want to start using Sencha Touch.

As you replied we can scroll these areas with 2 finger swipes.
But how would be user know which area is scrolling.
Please tell me the different ways to use scroll bar in combobox in Extjs.
My Aplication is almost complete using Extjs so now i cant start with Sencha Touch.

Those are native HTML comboboxes, they will always work. Ext JS combobox is not using the native one, it's rather a bunch of DIVs trying to mimic a combobox.
