Hi Nguyen,

Greetings from Syncfusion. 
We have analyzed your requirement from the attached screenshot in the last update. The SfComboBox’s DropDown opens from the control position and we do not have the support for positioning the dropdown. Hence, we have achieved your requirement using SfPopupLayout and ListView. Please have the sample from the below link.

Sample Linkhttps://www.syncfusion.com/downloads/support/directtrac/general/ze/ComboBox_1485321388367191

Code Snippet: 
 <sfPopup:SfPopupLayout x:Name="popupLayout">

        <sfPopup:PopupView ShowFooter="False" ShowHeader="False"> 
                     <ListView x:Name="listView" ItemSelected="listView_ItemSelected" ItemsSource="{Binding BookInfo}" SeparatorColor="White"> 
                            <StackLayout HeightRequest="40"> 
                                <Label Margin="10,7,0,0"  
                                       Text="{Binding BookName}"  
     <StackLayout x:Name="layout" Padding="10,60,10,10"> 
       <Button x:Name="PopupImage" WidthRequest="30" HeightRequest="30" HorizontalOptions="End" Clicked="ClickToShowPopup_Clicked" /> 


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