Subject: Add "valo-menu-hover" stylename to make responsive menu appear w/o adding code (... 
X-Git-Tag: 8.0.0.alpha5~11
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=53f990042418c66939292189879c296a85b654dd;p=vaadin-framework.git

Add "valo-menu-hover" stylename to make responsive menu appear w/o adding code (#19019)

Adding the optional "valo-menu-hover" style to the "valo-menu" element
will make the menu appear on hover - i.e when mousing over on desktop,
when tapping on touch devices (which also triggers hover).
