Hello All,

I would like to develop facility to set UDT parameter **value** through dropdown, like the UDT datatype. Does it possible? Please refer screenshot. Please advise/guide to achieve this facility.

If you are trying to build an interface this is possible. You can create the interface and use scripting to generate either new tags or modify existing tags.

Take a look at system.tag.configure

> Creates tags from a given list of Python dictionaries or from a JSON source string.
