Column Search with drop down based on Column Selection

[trselva]

Is it possible to have a drop down (:enum) of distinct values for column search based on the column selection. I tried something as below. But it did not worked.

filter(:column_selection, :enum, select: :columns_select, dummy: true)
filter(:column_search, :enum, select: :columnvalues_select, dummy: true) do |value, scope, grid|
  if (grid.column_selection)
    scope.where(grid.column_selection => value)
  end
end

def columns_select
  columns.map do |column|
    [column.header, column.name]
  end
end

def columnvalues_select
  columns do |column, grid|
    if (grid.column_selection)
      if grid.column_selection == column.header
        colvalues = Countrytable.select(:"#{column.name}").order("#{column.name}").distinct.all.map(&:"#{column.name}")
      end
    end
  end
end

Also How to refresh or reload column search on change in column selection without page reloading (without form submission)?

Please update whether it is feasible to do with datagrid.

I have no idea what are you trying to build. Please build the interface you want with a tool like https://jsfiddle.net/ and share it with me.
