I want to implement a drop-down list with filling its option strings dynamically.
The strings are stored in a string array of a UDT that from OPC tags
Take below snapshot as example, I want the “String 1” and “String 2” to be displayed in the drop-down list.
I could get the “string 1” & “string 2” from OPC tag with JsonGet function separately by the array index.
I tried to use data set of the drop-down list widgets, it seems that it only support static strings or the dynamical string from SQL database as shown in below link
Is there any way that I could fill these dynamical strings from the OPC UA tag in the property of the dropdown list widget?
