How to populated a multi-row category set

Hayden Ross

Hi,
I'm looking for the easiest way to populate a multi-row category set using content servers rest api and javascript. Here is a screenshot of the categories I want to update (I want to populate the "By Row" set):

Can I pass an array of objects to update the set?

Yes. When modifying an already populated multi-row attribute set, make sure, that you send all rows, regardless what row was changed. For example, updating a multi-row attribute set with two rows, which has attributes of types User and String:

...
"422557_7": [
  {
    "422557_7_x_8": 208721,
    "422557_7_x_9": "First User"
  },
  {
    "422557_7_x_8": 208721,
    "422557_7_x_9": "Second User"
  }
],
...

If you want to learn, how varioues types are formatted, look at the data property from the category editing form API response - .../api/v1/forms/nodes/categories/update?id={node_id}&category_id={category_id}.
