      Hi

      In the CCDD configurtation I can enter a default value that is shown when there is no value selected.
      Now in my case there should always be a value selected, depening on the first field the secoind should have a default value chosen.

      To be presice: I have a CCDD with country and city. The available selction of cities depends on the selected country. There is only one County to select and one city to choose. This works fine with the given CCDD. (Working on a lib here)
      Experice showed, that in every country there is one city with the most entries, so the users would like to have this value pre-selected. Meaning if you select the country, a given default value (city) is automatically filled in the city field (if there is nothing chosen so far).

      I tried to use a cunstom function to read out the country, and then use a switch statement to fill in the city field. I put that function with a rule that triggers on the country not empty (or changed). I also tried it with an onLoad trigger rule, where I know the country was already filled in. It doesn’t select the city with the form openend.
      BUT when I save the form, I then have the default value saved (if there wasn’t anything selected before)

      Maybe I’m thinking in the wrong direction here, not seeing the obvious
      Would you have any tip how I can accomplish that?

      Thanks

      Hi Nicole

      If I understand your situation correctly, Alexander has already thought of this and included it as standard;
      -In DFFS config there is a check box for “Autofill subsequent dropdowns when they contain only one valid option”
      -Standalone there is a parameter to set – “autoselectSingleOption:true If the next dropdown contains only one option it will be automatically selected.”

      Have you tried either of these?

      See guide

        Hi Adam

        Yes I do use this, but this only helps if the 2nd dropdown has only ONE value – which for me is only the case for one country. For all other countries there is more than one city available in the dropdown.

        So while it’s really handy to have the value pre-selcted if there is only one, here I would need to be able to pre-define the value that is going to be pre-selected, even if there are more values to choose from. (Since it’s a default and not a fixed value)

        Thanks

      Hi,
      I don’t think I can add this as a built in functionality so you would need some custom code. If you could provide a “mapping” for each selected option, and the value to preselect I might be able to create a code snippet.

      Hi,
      Add this code to your Custom JS:

      // Maps default city
      var mapDefaultCity = {
          "Bulgarien":"Sofia",
          "Bosnien-Herzegowina":"Sarajevo",
          "Kroatien":"Zagreb",
          "Polen":"Krakau",
          "Serbien":"Belgrad",
          "Slowenien":"Ljubljana"
      };
      
      $("#dffs_COUNTRY").on("change","select",function(){
          var country = $(this).find("option:selected").text();
          if(mapDefaultCity[country] !== undefined){
              setTimeout(function(){
                  setFieldValue("CITY",mapDefaultCity[country]);
              },500);
          }
      });

      Change “COUNTRY” and “CITY” for your fields names – and fill in more countries and corresponding cities in he map-object.

      Let me know how this works out.

      Best regards,
      Alexander
