Catalog Item to show subcategory based on categories without dependent value.

[SD_Akshay]

I have created Variable choices for Category and Sub- categories in specific variable. Normally when we create choices it gets created on Choice table. But here dependent value option is not the case.

How can I populate Sub categories based on Categories when I don't have dependent value. 

1. I have tried client script and it is working fine as expected. But my sub-category choices are more than 150+. So the client script have became more than of 900+ lines.

(Method used in client script addOption/removeOption)

2. We can't use reference qualifier since the choices aren't on Choice table and don't have dependent value.

3. No requirement to create Custom table. 

Please give solution

I was able to achieve this using maintain item catalog variables itself, I created the variables in sys_choice table itself and fetched them from variable by giving it type as "Lookup Select Box" and in "Type Selection" related section had the below configurations

Lookup from table : Choice

Lookup value field : Value

Lookup value field(s): label

Reference qualifier: javascript:'name=incident^element=subcategory^dependent_value=' + current.variables.category;

And if the third field is there which is dependent on sub-category I would add in Type Specification section

Variable attributes : ref_qual_elements=subcategory

With this I did not had to add any custom table or any choices in maintain item variable.
