Hi Eswara,

Thanks for the reply,

I have edited the sample provided to demonstrate the issue,

<combobox:SfComboBox HeightRequest="40" x:Name="comboBox" SuggestionBoxPlacement="Top" IsEditableMode="True" >
                <ListCollection:List x:TypeArguments="x:String">
                    <x:String>Great Britain</x:String>
                    <x:String>United Kingdom</x:String>

It occurs when the Combobox is being filtered/searched

Hi Shane,

Thanks for your update.

The reported issue is not occurred due to IsEditableMode property, it is occurred because of less space available at the top of the SfComboBox control. As per the current implementation if the dropdown view height is larger than the space available at the top of the SfComboBox control, then the dropdown view will automatically displays at the bottom. Else it will be displayed at the top with the available space at the top of the SfComboBox control. This problem can be solved by using the MaximumDropDownHeight property. Based on the available space at the top of the SfComboBox control set the max height of the drop down view using MaximumDropDownHeight property. Based on your requirement we have prepared a sample in which we set a value for the max height of the drop down view to show the dropdown view always at the top. Please have from the below link.

Please check the sample and let us know if you have any concerns.

the Xamarin.Forms.Application.Current.On<Xamarin.Forms.PlatformConfiguration.Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize) line has an issue when I use SfTabView, the comboboxes with multiple selection couldn't render correctly (the inner space turns white) and the items are render correctly when I change the tab and I return to the container tab (where combobox is).
