[Sub-Window, Sub-Menu] Custom Component


I want a “sub-window” or “sub-menu” like this (Outlook):

When I click on the Button, my app open a Vaadin component, sub-window:

but I want something better like the Outlook…bringing the component from the top to the bottom.

There is an add-on (for example) that I can do it?

Thanks in advance!

If you mean with ‘bringing the component from the top to the bottom’ that you’d like to change the styles so that the popup seems to be on the same level with the opening button and directly underneath it, I’m afraid I can’t think of any such add-on. You might have to remove the shadow and do the repositioning yourself within your own theme.
