I'm building a web app using Vaadin framework version 14. I would like to use a layout component add-on that was written for Vaadin 8. I know it's not that easy since they change the approach from basing on the client engine to render everything natively in the browser. But is there a way to add this component anyway? I've searched for any solutions to migrate older components but all I found was just an annotation that they are no longer using old layouts. I have tried using HtmlContainer Class to create my own CustomLayout as it's says here but I can only add elements that extend com.vaadin.flow.component.Component and not com.vaadin.ui.AbstractOrderedLayout. Do you have any ideas how to make it work?

Kind regards, Marek

You can run a Vaadin 8 or 7 components in Vaadin 14 with Multiplatform Runtime (MPR). That product requires a Vaadin Prime subscription.

I wouldn't recommend that for a new project written in Vaadin 14. Try to find other alternatives written with Web Components or Javascript. You can integrate an existing Web Component into Vaadin.

  • Here is the product page for MPR if that sounds like an option, but it does seem a bit heavy-weight solution for just a progress bar: https://vaadin.com/multiplatform-runtime – Anna Koskinen Jul 23 '21 at 11:48
  • Is there any other place to search for such alternatives except for the add-on directory search (https://vaadin.com/directory/search)? – kupkol Jul 23 '21 at 12:29
  • @kupkol You can [integrate an existing Web Component](https://vaadin.com/docs/v14/flow/web-components/integrating-a-web-component) into Vaadin. – Basil Bourque Jul 23 '21 at 22:10
  • I will try that. Thanks for the advice. – kupkol Jul 26 '21 at 09:32
