If we have a DropDown inside a form, which has the values form.SetFieldTextColor(tcell.ColorBlack) and form.SetFieldBackgroundColor(tcell.ColorWhite), when we click on it and exit without selecting an option, it takes the 'FieldTextColor' value and causes a hiding effect. I believe the effect can be better appreciated with the video.

   app := tview.NewApplication()
dropdown := tview.NewDropDown().
	SetLabel("Select an option (hit Enter): ").
	SetOptions([]string{"First", "Second", "Third", "Fourth", "Fifth"}, func(text string, index int) {
	
})
dropdown.SetLabel("DropDown: ")
inputF:=tview.NewInputField()
inputF.SetLabel("InputField")

form:=tview.NewForm()
form.AddFormItem(inputF)
form.AddFormItem(dropdown)

form.SetFieldTextColor(tcell.ColorBlack)
form.SetFieldBackgroundColor(tcell.ColorWhite)

app.EnableMouse(true)
if err := app.SetRoot(form, true).SetFocus(form).Run(); err != nil {
	panic(err)
}

@rivo Do you think this could be a possible bug? Or am I doing something wrong?

The latest commit solves your issue. However, this DropDown stuff is very old code and requires some refactoring. So things might still change slightly.
