Row filter for columns with non-nominal values

Hi, I wanted to ask if there is any alternative to the Widget/Setup Nominal Filter or Nominal Value Filter, to be able to filter categories in columns with many response types or columns of non-nominal values.
Is there any easy, effective and fast way to perform this task without having to create the conditional with the values to filter manually?

Hello
You solve it by recalculating the domain of the variable. By default KNIME takes at most 60 unique values to accept a variable as nominal. You can use a Domain Calculator node and remove the restriction on the number of possible values, or increase it as much as you need. Then you can use the filter node in both widget and configuration.
