You can uses nested data type for creating such a field and indexing list of object. Refer to the example below and modify it to your needs:

Mapping:

PUT testindex
{
  "mappings": {
    "_doc": {
      "properties": {
        "nestedField": {
          "type": "nested",
          "properties": {
            "field1": {
              "type": "text",
              "fields": {
                "keywords": {
                  "type": "keyword"
                }
              }
            },
            "field2": {
              "type": "integer"
            }
          }
        }
      }
    }
  }
}

Adding documents:

For single item in list:

PUT testindex/_doc/1
{
  "nestedField": [
    {
      "field1": "Some text",
      "field2": 10
    }
  ]
}

For multiple items in list:

PUT testindex/_doc/2
{
  "nestedField": [
    {
      "field1": "Some other text",
      "field2": 11
    },
    {
      "field1": "random value",
      "field2": 15
    }
  ]
}
