When i click combobox then scroll down to the page, dropdown of combobox goes down too. How can i fix this problem?

Are you referring to Framework ComboBox? In case yes, this is a known issue.

https://github.com/vaadin/framework/issues/5043

There is workaround available

https://vaadin.com/directory#!addon/comboboxpopuptracker-add-on

If you are referring Elements vaadin-combo-box, I am not sure, but it could be that there is the same issue too.

Thank you! Demo is cool, that’s what I need. But I received the following errors when I added addon to my project:

I’m using vaadin 8.1.1.

The Add-on does not work with Vaadin 8. But there is no reason to worry. The bug I referred has now been fixed with solution similar to the add-on and it will be included in some of the upcoming versions of Vaadin 8 soon.

Thank you!

I am facing the same issue. But scenario is different in my case. My application is based on vaadin 8.4.5, but the combobox component is used from vaadin-compatibility component v8.4.5. Since the vaadin-compatibility package uses old v7 combobox component, the problem still persists. How do I solve this issue. Note that, I can’t remove the vaadin-compatibility(server/client) jars from my application, because it is the requirement of my application. I know this bug was fixed in later version of vaadin. But I guess this fix wasn’t for vaadin-compatibility components. For code details and information please see the thread

Please help !!!
