* Adds a select field type that may contain multiple values to the given htmlTable.
* The field name will be the same as the attribute name plus a counting number (e.g. street_0).
* The last field will be followed by a button to add a new value. This is named add_{attribute name} (e.g. add_street).
* There must be a help entry with the attribute name as ID.
* A new line will also be added after this entry so multiple calls will show the fields one below the other.
