Hi All Is there any way can we sort the list in the list field value in suitlet For ex if can we change the configuration of the list such as we can enter the alphabet and word in the list with same alphabet only comes in the list

The NS list field does not have that functionality. You might need a client library like https://twitter.github.io/typeahead.js

Need to use this in suitlet

You can load client libraries in suitelets as long as you provide the page with the data. However, if you are not confident with this, I would recommend just using the slow/janky default NS list field.

If you are using suitelet, You can add options in select field manually before you return the Form in Get Response of the Suitelet.
