I am building a site that has a header with a fixed position which contains a select menu. The header is supposed to stay locked to the top of the screen due to the position:fixed in css. However, when clicking the select menu in mobile safari on iphone, the header no longer stays locked to the top when the ios select menu opens. It seems that ios is centering the div with the select menu onto the visible area of the screen above the menu. This doesn't happen when the page is scrolled to the top, but when the address bar is not visible, it "breaks" like so. Haven't found any other answers, maybe I'm asking the question the wrong way. I can't post links to code yet, any help is appreciated.

For now I don't think there is a perfect solution to deal with the focus jumping.
In my case I hide the header on focus in and show again in focus out and it works well.
I don't know if in your case this could be a workaround.
You can try this:
// detect ios device
if(navigator.userAgent.match(/(iPad|iPhone|iPod)/gi)){
// hide header on focus in and show on focus out
jQuery("#content").focusin(function(){
jQuery('#your-header-id').hide();
})
jQuery("#content").focusout(function(){
jQuery('your-header-id').show();
})
}
The #content is a div where you should have all your controls, the jQuery .focusin() detects the focus event on parent elements, so every control will trigger the focus event. You hide the header on focus and show after that. Hope this helps!

we have a page with a search box. search box is displayed using an iframe. on that search box, we have multiple select boxes.there is a select tab to select children.if user select the option for "more", another dynamic div will be displayed. when this div is loaded, scroll bar is displayed so user can scroll down to add more. this is working fine on all browsers, but scroll bar is not displaying when we test that page using ipad or iphone.
what is the reason for thsi and how can we solve this?.
Thanks

may be in css used overflow:hidden;
You need to remove it,

On this site : mecanomedic.com, the menu template work fine in "normal" desktop browser, but dont slide down on ipad-iphone device. What can be the problem ?
Some tell me it's a css problem, but HOW safari desktop work ?
The problem is that the menu expansion relies on the user hovering with a mouse. On touch devices like iPads & iPhones, the hovering gesture can't be replicated because there's only one input- touch. If I were you, I'd take a look at Twitter's Bootstrap menu setup and perhaps use media queries to serve up a different menu on smaller screen sizes.
Here's an example of a Bootstrap navigation bar in action (you'll have to inspect the code to see how it works).
Add a href to the top-level <a>'s so that they can be focusable:
Produits
Elements that are focusable receive mouse events and hover styles when the user taps on them.
As #Matt stated, the problem is that your menu relies on a hover event and unfortunately that event is unavailable on touch screen devices.
One way to fix this would be to:
Check if the current user's device is an iOS device
If the device is an iOS device, use javascript to trigger a menu item's "show event" when the menu button is CLICKED instead of ROLLED OVER / HOVERED.
This would result in the menu being shown when the user taps a menu button.
There's an issue when accessing my website (http://www.zero11arquitetura.com.br) on iPad or iPhone with iOS 5 that I can´t fix. When window is scrolled thru code every position:fixed elements click event stop working. Can you please help me ?
This site structure uses a top menu div and a header div with position: fixed css. When user clicks on a menu item window scrolls horizontally until it reaches its target.
Clicking in the menu item is done by jQuery click method on each img tag and scrolling is done by jQuery animate method ($("html:not(:animated),body").animate({ scrollLeft: varDestino }, 1500);)
When page is loaded the menu works just as I intended but, after it scrolls thru menu, and I try to click on another menu item nothing happens. The strangest thing is that everything works again when user manually scrolls the window (by finger).
It looks like that by changing window scroll position by code (jQuery calls window.scroll) fixed elements lost its clickable position references.
Is there any workaround for this ?
Thanks,
I've solved this with a trick. I've created invisible divs over the menu items that changes it's position when page scrolls (simulating afixed element over the real position: fixed menu items). When user clicks or hover over those invisble divs the real ones are called
Is it possible to show a popup only in a certain gwt tab or a panel in that tab?
I've found methods to show a popups over the whole page, but not only in specific tabs.
When you switch the gwt tab, the popup should not be visible anymore and new popups should be able to be created, which again are only visible in the switched to gwt tab. Switching back to the other tab should then show the first popup again.
Optionally the rest of the tab, which is not covered by the popup, should not be clickable.
Are there any native methods for this? The gwt Popup Panel only seems to create popups for the whole page.
Edit: I've tried using smartgwts Window which seems to work just the way I want it to. When I switch the gwt-tab, the popup is no longer visible and returns when I switch back. The only problem is, that it isn't displayed right. The frame is placed on the far left side of the browser tab, while the content is displayed on the far left of the gwt-tab. If I move the content, the frame moves too. The frame is visible over the whole browser tab, while the content disappears if I drag it over the gwt-tab edge.
I guess it's because I'm adding a Window to a gwt-Panel. Is there any way to fix this without changing everything to smartgwt?
Not exactly, I think.
But, you can do something in the tab events, like hide the popup in tabs that it doesnt belongs. To avoid the lag of show/hide the popup, you can do this in the BeforeSelectionHandler, like this:
getView().getTabPanel().addBeforeSelectionHandler(new BeforeSelectionHandler<Integer>()
{
#Override
public void onBeforeSelection(BeforeSelectionEvent<Integer> event)
{
showPopupupsForTab(event.getItem());
}
});
In showPopupupsForTab you can show the popups for this tab (you can handle this with a map or something) and hide the others...
Something like this.
Hope it helps.
I am creating a wepapp, that has a horizontal menu. The menu is limited to 320px and has overflow set to hidden. Inside the links are wrapped in a div which has a width set to it. The list overflows on the x axis. I have applied a jquery plugin called OverScroll so you can drag this list left and right to reveal the hidden menu items.
It works great on a desktop browser but I am having difficulty on getting this to work on the iphone.
I have set up a demo at www.irfanyasin.com/iphone/
Any ideas?
Thanks
Apart from general usability issues (will people know it's slidable? I could see how this can be annoying if you use that menu often and have to slide it a lot), dragging doesn't work on most touch interfaces. You could try adding left and right buttons that scroll the menu when they click them maybe?
Also your demo doesn't work in Chrome on my desktop. Is the menu supposed to slide? It won't.
