Hello Cojocaru,
you can try update the relevant components and widgets,
https://docs.mendix.com/refguide/upgrading-from-9-to-10/#upgrade-widgets
for date picker please try this work around solution,
.mx-icon-calendar {
font-family: "Glyphicons Halflings";
}
.mx-icon-calendar:before {
content:"\e109";
}
Similar way add other missing icon with alternate icons,
.myclass .glyphicon-share-alt:before {
content:"\e109";
}
Thanks & Regards,
Manikandan K
Hello Cojocaru,
Was the custom CSS the right fix for you?
Also were you able to resolve the menu item width issue as well?
We are having the exact same issues in out Mx10 upgrade and would like to know what all helped fix them
Thanks!
