Making use of Javascript:

In a table structure, create a name textbox, an insert button and a name list. The name textbox cannot be empty and must not have duplicate names, validation is required (error message will appear). When the users clicks on the insert button, the name will be displayed in the name list using bullet point. The name list can store infinite names.

Sample output:(Empty field)
