Can I use GWT code in Vaadin 7 code?

Vaadin 6 / 7 / 8 Framework UI
1

I wanted to migrate a project from JSF and Primefaces to Vaadin 7.
In GWT I can create autocomplete, in the standard Vaadin there is no autocomplete
Can I use for example the SuggestBox from GWT in Vaadin ?

You should follow this wiki article,
Integrating an existing GWT widget
, to use the SuggestBox Component in Vaadin.
Something similar in “plain” Vaadin could maybe be realised by a Combobox or a PopupView, displaying suggestions to your entry.
