string html = auto.HTML; // <input> + <datalist>The members you reach for most often.
Name sets the input's name; Label_ renders a form-label above it; Value pre-fills the field.
Items (a TStringList) holds the suggestion strings that become <option> entries inside the <datalist>.
Placeholder shows hint text; MinLength sets how many characters are typed before suggestions appear (defaults to 1).
AutoCompleteID sets the element id shared by the input and its linked <datalist>; it defaults to sgcAutoComplete.
HTML returns the mb-3 wrapper containing the label, the form-control input and the populated <datalist>.
Inherited Section, ColumnWidth and RowGroup place the field on a TsgcHTMLPageBuilder grid.
