Hi,

I have a form with dropdowns and inputfields and want automatically write a config file out of the inputs.

With form.GetFormItem(1).(*tview.DropDown).GetCurrentOption() I get the current option of my dropdown.

My Problem is to differntiate between the FormItems to get the content of them.
How can I manage to do something like in the pseudocode?

Pseudocode:

for _, formitem =: range form { 

       if formitem.getType() == "dropdown" { 

                contentToWrite := formitem.(*tview.InputField).GetText()

       } else {

                contentToWrite := formitem.(*tview.DropDown).GetCurrentOption()

      }
}

Found the solution by using the reflect package.

reflect.TypeOf(form.GetFormItem(i))

You can also use type switches. That's probably faster than using reflect.
