multi drop down selections

Question

Hi team, 
 My use case requires me to select multiple options like: north, south, east ,west which am able to configure and it's working perfectly. 
 But there should also be an option to select all(I.e North, south, east, west) and based on it data should be displayed. 
 Can someone help with the code.

Hi, 
 I think this piece of code should work for you a!localVariables(
 local!choiceLabels: { "All", "East", "West", "North", "South" },
 local!choiceValues: { 0, 1, 2, 3, 4 },
 local!dropDownValue,
 local!value,
 a!multipleDropdownField(
 choiceLabels: local!choiceLabels,
 choiceValues: local!choiceValues,
 value: local!value,
 saveInto: {
 a!save(
 local!value,
 if(
 contains(
 save!value,
 index(local!choiceValues, 1, {})
 ),
 0,
 save!value
 )
 ),
 a!save(
 local!dropDownValue,
 if(
 contains(
 save!value,
 index(local!choiceValues, 1, {})
 ),
 remove(local!choiceValues, 1),
 save!value
 )
 )
 }
 )
) 
 In this, I have added an "All" label in the first index of the array of labels and values, and because of that, I have taken two variables. One for showing the correct value in the dropdown and the second one is to refer to other places where the value is required. 
 Thanks
