[Solved] Open specific combobox in upwards direction

[Munish]

Hello,
I have requirement to open specific combobox if the form in upwards direction. I am using

Html.Telerik().ComboBox() for MVC

I can add css or class however my requirement is to open only one dropdown of the form upwards and all other downwards(as they are working now) can someone guide me how can i do this. I know it uses "t-animation-container" where i can set margin but it does not have id of my control, how can i distinguish this from other combobox.

Thanks
