In this blog, I am going to show how we can filter a field (multi-select option set) item dynamically based on another field (single-select option set) item. Let’s consider a use case, We have a field named ‘Application Area’ which is a (single-select option set) field and ‘Application Type’ which is a (multi-select option set) field. Let’s have a look at JavaScript where the magic is making this possible. Step 1: Below is the entire code of JS For Table/Entity Main Form customization, select ‘Form Properties’ to include JavaScript function as below, On Load: oApplicationAreaType.Main On Change of field ‘Application Area’: oApplicationAreaType.getDetails Note: Pass the execution context for calling the JS function. That’s all, we have created a dynamic filtering of multi-select option set using JavaScript. Hope this helps!!
