ComboBox Rocks!

I am working with a project(vaadin8 & Spring boot) now.I want a ClickListener by combobox.Suppose, When i Check this Combobox it Will Show a Form under The combobox with some information like Firstname,Last name etcc…can i do this? if then how?

Thanksin Advance.

I think you need a focus event listener on the combo box, where you then make the form visible. Or, if you first want to make a selection in the combo box and show a form based on that, then you need a change event listener instead.
