            title

          }  

        }

    }

}

result:

{

  "data": {

    "boards": [

      {

        "items": [

          {

            "id": "xxx",

            "created_at": "2022-01-07T15:28:19Z",

            "name": "www.----.nl",

            "column_values": [

              {

                "id": "assessment_mi",

                "value": null,

                "text": "Maintainance",

                "title": "Assessment MI"

              },]

So I want to filter the word maintainance in grapQL or in php. So that I can count all the items that have the column value “maintainance” (because their are a lot of other values). Is their a way to filter such specifics. Because this is how I count items in php:

count($responseContentt'data']t'boards']d0]]'groups']p0]]'items']);

$totalNumber = count($responseContentt'data']t'boards']d0]]'groups']p0]]'items']);
