pickerFieldCustom: selected value is getting replace with identifiers value

The labels for the selected items are defined by the "selectedLabels" parameter.

Example: https://docs.appian.com/suite/help/25.2/recipe-configure-an-array-picker.html

also in this example https://docs.appian.com/suite/help/25.2/recipe-configure-an-array-picker.html

it is a client side filtering where system is getting data before user entry , i am looking a server side filter 

Note from https://docs.appian.com/suite/help/24.2/Custom_Picker_Component.html 
If you are trying to decide whether to use a dropdown with search or a picker component, keep in mind that the dropdown search runs client-side and the performance cost of loading options happens on initial load whereas the picker search runs server-side and the performance cost of loading options happens while the user is searching. For small sets of options, we recommend using the dropdown component

Hi gauravp915957 ,

In pickerFieldCustom, there's a parameter called selectedLabels (a list of text strings) that accepts an array of labels corresponding to the currently selected items.

To populate this, you'll need to run an additional query using the selected item IDs as a filter to fetch their corresponding labels, and then pass those to the selectedLabels parameter.

This approach is also outlined in the recipe shared by Stefan. However, note that the recipe uses static data—you’ll need to implement a dynamic query that refreshes on every value change.
