    [FIXED] [#720] DropDown's component is not collapsed on scroll

    On FireFox, run the following example



    Expand Field 6's component


    Using mouse weel / scroll weel, scroll the form. DropDown's component is not collapsed.


    On IE and on Chrome, everything works as expected.

    Thanks in advance.

    Hello, Raphael.

    Do you agree that this issue is very similar -- maybe related or possibly same -- to the other thread you opened, ToolBar overflow?

    I don't. In my option there is no relation between the issues.

    Hello everybody,

    Created an Issue - ComboBox's list or DropDownField's component doesn't collapse on scroll in Firefox.

    As a workaround you could try to listen to Window.getEl()'s scroll event and collapse the DropDownField.

    Good news! According to Sencha, this issue has been fixed. It just took some time to point the thread to the right issue! A double check can always be used but we're pretty confident the issue should not be reproducible in Ext.NET 4!
