You can look at this example in our demo

 
In setSelect command there is a parameter to add custom strings again with those from the db like this:

 
More you can getr from the API here

Kind Regards

Hello,

Sorry. I have not read carfully.

The additional values are available only when searching, so it can not be used when editing. For now I can recommend you to do this via the SQL. Using the above example you can use the following SQL in setSelect

Hello,

We will try to include the additional options in editing too.

Kind Regards

Will
