Related to Service catalog on visibility and mandatory fields

[varshajain]

In my service catalog, i have two select box field, for eg, 1 . is categery which has two options anad 2. is sub category which has 5 options.
now based on these conditions , the form visiblity and mandatory should work according.
Like it becomes 10 conditions on this, most of the variables are common and its visibilty and mandatory works on different cases.
I worked with UI policy and Client scripts and it is not working as expected.
How can I achieve this, and variables whose visibilities I need to do has almost 12 -1 5 variables.

I’d suggest using separate Client Scripts for each field instead of trying to manage everything through a single UI Policy. Client Scripts give you more control over complex combinations, especially when multiple fields need to show/hide or become mandatory based on different training type and format values
