hi everyone, If I need to populate a list field dynamically, depending on what they select in other field, what is the best way? How can I do it with client if I can't do a search.create? to populate the field

Without scripting, the basic idea is to use the Sourcing/Filtering configuration of the custom field; specifically, the "Compare to Field" feature therein. There are some Help docs that illustrate the idea. There's also an RSM article and a Prolecto article that walk through it as well.

Ok thanks, understood , but what happens if for example the first field has two options: Shoes, Shirts, and I want the second field to filter according to what I chose in the first because it has mixed options for both shoes and shirts, and apart from that each field points to a different record that is linked to the main one, wouldn't it be better to use a script?
