How to filter array of data from one id in grid

Hi appian.user , 

I'm not clear with your expectation, But let me try solving based on my understanding.

So, you want a dropdown filter. In which, it should filter the record. And on that particular record, you just need to display only the selected value from that list of values in the array of that respective record. Am I right?

If that was the case. In the particular column of that grid, use the index function. Here, Provide the data as that Array list and Index as that Selected value. 

Hope it helps

Can you share the code of your filter?

sure here is the code for filter:

here SLS_QRY_getWorkOrderDropdownData is ER for calling field of that particular table , I have attached code for this ER as well

a!localVariables(
  local!queryResult:
  a!queryRecordType(

        a!grouping(

      }

    ),
  ),
  local!activityIDDropdownMultipleValues: if(
    length(trim(split(

      ";"))) > 1,
      trim(split(
        local!activityIDDropdownValues,
        ";")),
        local!activityIDDropdownValues
  ),
 
 a!columnLayout(
                    contents: {
                      a!multipleDropdownField(
                        choiceLabels: union(local!activityIDDropdownMultipleValues,local!activityIDDropdownMultipleValues),
                        choiceValues: union(local!activityIDDropdownMultipleValues,local!activityIDDropdownMultipleValues),
                        label: "Activity ID",
                        placeholder: "--Select Activity ID --",
                        value: local!currentActivityID,
                        saveInto: {
                          local!currentActivityID,
                          a!save(local!selectedActivityID, null)
                        },

                    width: "AUTO"
                  ),

Where and how do you apply that filter? I would expect to see an a!queryFilter() somewhere.

Posting 700 lines of code here and then expecting me to read all of it is an imposition!

It seems like you store multiple "maestroRefId" values as a semicolon separated list in the DB. I do not see any queryFilter in your code. You will have to adapt that filter to your way of storing data.

BTW, doing a database query in a grid column value calls for bad performance.

The rule SLS_QRY_getWorkOrderSync() for the local getWorkOrderDetails, you are passing the selected Activity Id in it, is this rule returning data when you input 213396  as activity id?
