Select subset of columns in table based on a filter's value


I have a filter with 5 options, let’s call them A, B, C, D, E. I would like to select a different set of columns if a table based on the option selected in the filter. The logic should work like follows:

  • If option_selected != “D” OR no option is selected → Display columns level1, level4.
  • If option_selected = “D” → Display column level1.

I am able to access the current selected option of my filter like so: '{{filters.ele_filter_id.column_name.values | list }}', but how can I select a subset of columns via my table’s custom query ($sql) ?

I have been trying out lots of different possible solutions, but always end up having column level4 filled out with a NULL.

unfortunatelly as far as i can say, there is no build-in feature provided by Apps to do so, but there might be means to do so once combining existing functions the right way.
@magdalena.soeldner might have some ideas based on the following code snippet:
"value": "[{\"name\": {{filters.FILTER_cols.column_name.values | list?separator=},{\"name\": }} }]"
Nevertheless I will bring it to the product to offer at some point in time a standard functionality to cover such an recurring use case.

Managed to solve the issue thanks to help by @kai.geukes with a quite “dirty” workaround in order to select a different subset of columns based on the value of a filter on the option_selected column.

  1. Add a column column_names containing the column names in the original data table that should be displayed based on the value of option_selected.
  2. Create an invisible filter on column_names and add it to the current page’s layout. To set the container of this filter as invisible, set the following property on the container:
 "id": "container_table_columns_mapping_invisible",
        "appearance": [
            "hide": true
  1. Set the syncset to apply=true and publish=false, "selectFirstByDefault": true, "multiSelect":false,
    on the newly created invisible filter, and sync it with the syncSet of the filter on option_selected.

  2. In the definition of the table being filtered, display the columns dynamically based on the column column_names of the newly created invisible filter, using the following SQL Query:

 "sourceOptions": {
    "$sql": {
      "type": "string",
      "value": "SELECT {{filters.ele_filter_column_names.column_names.values | first }} FROM inputTable i"
