Populate field based on lookup

Forms

Hello @eweiler,

Values of the additional columns will be displays only after the data is saved.

If you want to show this values instantly when user selects an option in a lookup dropdown, you can use JavaScript and Extra fields property

Here is the code example:

fd.spRendered(function(){
  fd.field('LookupField').$on('change', function(value){
    //populate Text field with the Extra field value
    fd.field('Text').value = value.ColumnName;
  });
});
