available values

I would like to know if it is possible to apply a filter to an external API variable of the UI Designer in the field "Avalaible value" so that only data that matches the one selected previously is displayed.

I need this because I am developing a screen where there will be several lines, as if they were items of an order, and for this I need the filter to be made according to what was being selected previously but in that line. I have an example that works exactly as I need it however the content is brought from a JSON variable and not a REST API.

Hi,

I have a "connector in" which sends the a query result (list) to one Process Variable.
The resulting array has 2 "columns".

When calling the Process variable from the UI form, using a UI variable (with External API call), I don't know how to parse the result.

The select widget is supposed to show a list of departments. i.e.:
Aires Acondicionados"
Administrativo
Aprovisionamiento
...etc
