How to hide certain options from a list collector variable based on the selection choice of a prior variable inside the same catalog item?

[alantpham]

I have a select box variable that represents the type of access a user may want to request. I have a list collector variable that references an entire list of companies a user could possibly choose from.

I want to only show certain companies the user can choose from based on the choice made from the select box variable. This is because only certain "Types of Access" choices have access to certain companies. In the table itself, there is no attribute to associate which company is available for what type of access. What would be the best way to go about this?

A visual solution of a similar situation would be greatly appreciated as I am quite a novice with SNOW.

A question: If there is no attribute in the table (with the list of companies?) that specifies which type of access is available, where does this information live?

If it's not anywhere in ServiceNow, you could hard-code the reference qualifier, i.e. Access Type 1 shows company A, Company B and Company C, Access type 2 shows Company D, and Company E and so on, but if you've got more than a handful of companies that gets very difficult to build and maintain. 

My instinct then, is to add a column to the companies table that contains this information. Then, it's relatively easy to build a reference qualifier on your list collector that depends on the Access type choice.
