I currently am using the dropdownlist and cannot seem to change how long the dropdown list is when it is selected. It only shows the first 3 or 4 items and then cuts the rest off with the option to scroll down. I would like to increase the height of this so it can show more options at once when a user is using the search bar to filter

 I tried to use the setting .PopupHeight() and it doesnt seem to do anything but here is what my code is, what do I need to do to make the change that I need?

@Html.EJ().DropDownList("MenuItemsList").Datasource((List<MenuItemsDropdownModel>)ViewBag.RecipeDropdown).DropDownListFields(df => df.ID("MenuItemID").Text("Name").Value("MenuItemID")).ClientSideEvents(e => e.Change("onMenuItemSelect")).EnablePersistence(true).EnableFilterSearch(true).PopupHeight("600px").WatermarkText("Select a Menu Item").Width("100%")

Hello Nate, 

Thank you for contacting us. 
We have checked the reported issue in our end. This issue may occur due to enablePersistence property set to true in your sample and this maintains the previous height of DropDownList popup from browser cache. We suggest you check this in “Incognito window” and confirm it. You can also clear cache in your end, so that the sample will be rendered with the popupHeight, set in sample during initial rendering. We have used the below code in our sample. 
@Html.EJ().DropDownList("MenuItemsList").EnableFilterSearch(true).Datasource((List<Data>)ViewBag.RecipeDropdown).DropDownListFields(df => df.ID("MenuItemID").Text("Name").Value("MenuItemID")).WatermarkText("Select a Menu Item").Width("100%").EnablePersistence(true).PopupHeight("600px") 
We have attached the sample for your reference, please find the sample at the following link: 
DropDownList is rendered as shown below 
Please check this sample in your end and let us know if you need further assistance.
