I have placed a dropdown button in appbar which shows a dropdown list. In the body of my page, i am displaying a iframewidget using htmlelementview . When i click the dropdown button,the dropdown list is displaying over the iframe widget(which is the body of the page) and if i select the option from my dropdown list,there is no gesture detection(because it is displaying over the iframe) .
How to solve this?
You can wrap the dropdown list in a PointerInterceptor from pub.dev: pointer_interceptor

I want to show my own page on dropdown button tap, then item selected on page should be set as dropdown button value.
So basically, I need DropdownButton without any popup on tap. When I use onTap still default popup will be shown, how to prevent that?
why you don't use a button instead? or you can try to create an Inkwell put a container on its child and make it look like a button and write your code inside Inkwell OnTap(){}
1- Pass null to items parameter to disable the button.
2- You'll notice icon's color will be grey with disabled button, you can change it by setting color of the icon you send to icon parameter or send color directly to iconDisabledColor parameter.
3- You'll not use value parameter, instead you'll just use hint to show both your hint and your value. and update it using your state management after you pick new value from your own page.
4- Wrap your DropdownButton with GestureDetector or InkWell to show your own page when you tap on the button.
5- If you want to customize your DropdownButton shape, size and more. You can try my new package DropdownButton2. It's simple, easy, based on Flutter's core DropdownButton and have lots of features.

Flutter includes a dropdown button, but can we add searching functionality to it? Where can I start?
You should create a StatefulWidget (button for example) which its root widget is a GestureDetector, then showDialog on button tap.
Dialog should contain a list of items as state and a ListView.builder() to build items. When you search you should render items with items.where() to filter items.
I know there is DropDown Button but how dropdown button work is it show content in popup style and i want to implement autocomplete textfield and want to interact with textfield while suggestion come under textfield.
There is a package available for this that you can use and it works very nicely.
You can also fetch the suggestions list from API.
Here is the link

I have yahoo autocomplete widget on my web page. if you click on Button a dropdown appears. Now if the page on which dropdown appears have scroll bars and you try to scroll, the whole page gets scrolled But the Dropdown retain the same place.
I have instantiated the auto complete widget as following:
new YAHOO.widget.AutoComplete("inputBox.id", "inputBox.container_id", dataSource);
So how we can make the dropdown move with the text field while scrolling?
Thank you
Got the Problem, the position style of yui-ac-container was override in my case. Because of that the dropdown was floating in the air. Changed the postition attribute from fixed to absolute and it work as expected.
