Adaptive Mode
The Telerik UI for ASP.NET Core DropDownList supports an adaptive mode that provides a mobile-friendly rendering of its popup. Which will accommodate its content based on the current screen size.
To set the adaptive mode, use the AdaptiveMode() option.
@(Html.Kendo().DropDownList()
.Name("dropdownlist")
.DataTextField("ProductName")
.DataValueField("ProductID")
.AdaptiveMode(AdaptiveMode.Auto)
.DataSource(source => {
source.Read(read =>
{
read.Action("Products_Read", "DropDownList");
});
})
)
<kendo-dropdownlist name="dropdownlist"
adaptive-mode="AdaptiveMode.Auto"
datatextfield="ProductName"
datavaluefield="ProductID">
<datasource>
<transport>
<read url="@Url.Action("Products_Read", "DropDownList")" />
</transport>
</datasource>
</kendo-dropdownlist>
