Feature Request: Send Multiple URL Query Params in OpenAPI Imported Collection

[Xenox003]

Hi there

Situation

When testing endpoints that accept array-type query parameters in an Imported/synced OpenAPI definition, there is currently no way to send the same query parameter key multiple times.
Many APIs represent arrays in URLS by repeating the parameter name:

GET /hubs/{id}/purchases/?productIds=abc-123&productIds=def-456&productIds=ghi-768

In the current Scalar API client UI, there is no mechanism to:

• Add a duplicate query parameter key
• Input multiple values for an array-type query parameter

Viable solution

When a query parameter is defined, in the OpenAPI spec as type: array, then client UI should allow the user to add multiple values for that parameter - either through:

• An "Add item" / "+" button next to array-type query params
• A comma-seperated or multi-line input that serializes into repeated keys (e.g. ?ids=a&ids=b)
• A tag/chip input where each chip represents one value in the repeated param list

Relevant OpenAPI spec example:

{
  ...
  "parameters": [
    {
      "name": "ProductIds",
      "in": "query",
      "schema": {
        "type": "array",
        "items": {
          "type": "string",
          "format": "uuid"
        }
      }
    },
    {
      "name": "hubid",
      "in": "path",
      "required": true,
      "schema": {
        "type": "string",
        "format": "uuid"
      }
    }
  ]
  ...
}
