In the Ajax control, you have the ability to filter a list and, if the term is not found, execute a command on the new term you typed in. This is in the Ajax demo at https://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/autocompleteclientside/defaultcs.aspx?_ga=2.149674102.1173080875.1622059656-840544784.1585530237 in the Autocomplete example at the top. I am not seeing this functionality replicated in the documentation for .NET Core. Is it possible to do something like this using a Tag Helper? If so, how would one go about it?
p.s. For example, if I enter email@example.com (not found in the list), and click Submit, the message "You have selected the following email: firstname.lastname@example.org" will be displayed.
