I can't figure out how to have the text display on a single line instead of on multiple lines.

When I list my choices, some fields take up three lines, which makes the list difficult to read.
<td width="205px" height="15px" TextMode="SingleLine">
@item.Adresse
</td>
I want all of the lines to be a single line in height.
style="white-space:nowrap;"?TextModeattribute is part of ASP.NET Web Forms, but you tagged this question with ASP.NET Core, and the@item.Adresseis part of the Razor syntax. These are not intercompatible. If you're using ASP.NET Core with Razor templates, you cannot use ASP.NET Web Forms attributes. (Though, even if you were using Web Forms, you'd have still required arunat="Server".)
