How to dynamically populate multi‑select rule options in a Catalog Item using data from an API

[srikanthvan]

I’m building a Catalog Item where I need to pull data from an external API. I’ve already created the REST Message and HTTP Method, and I'm successfully able to fetch data of first 2 variables using a Script Include and a Catalog Client Script.

My Catalog Item has three variables:

• Selection_of_site
• prompt_selection
• rules

The “rules” variable needs to display values returned from the external API based on selection of the site. The challenge is that the API can return dynamic values and the user must be able to select multiple rules.

However, the Catalog Item does not support a "(multi‑select choice)" variable type natively.

Please provide the information, How to configure it.

you can have either of this approach

1) Approach 1 -> create custom table to hold the values returned from API and use List Collector type variable so that user can select multiple values

OR
2) Approach 2 -> create variable of type Custom with label and use widget to render those values and allow multi-select there
