Wow thank you very much ! That is exactly the behavior I was trying to recreate. I now feel a bit stupid for not being able to do this myself as it's pretty straightfoward.. 

Again thank you for your help, I'm very happy to have this little feature on my webdropdown :)

Have a good day !

Hello Technical,

Our control doesn’t support the functionality that you required but after some investigation I found a work around. What you can do to achieve this functionality is to handle DropDownOpened event:

<ClientEvents DropDownOpened="WebDropDown1_DropDownOpened" />

And add the following code in it:

function WebDropDown1_DropDownOpened(sender, eventArgs) {

    var selectedItem = sender.get_selectedItem(); // get selected item

    if (selectedItem != null) {

        var itemElement = selectedItem.get_element(); // get item HTML element

        itemElement.scrollIntoView(true); // scroll to element

     }

 }

 I modified the code sample in order to show you the implementation. You could test it on your side and let me know how this suggestion works for you.

Hello Aneta,

I see that you have changed the automatic postback option for the selection changed event. I actually need it to work on the backend. 

After the postback is done, is there a way to call scrolltop on the webdropdown? Like use it to target the <div> containing the itemss after the initialize event of the control?

Thank you.
