Ui-related label is a non-scrollable placeholder for plain text. Like other components, it features specific label property that sets text value.
{ view:"label", label: "Label", inputWidth:100, align:"center"}
Label control can be used to render any user HTML or icons (as well as built-in in Webix Font Awesome icons):
{ view:"label", label:"<span class='myCss'>My Label</span>"},
{ view:"label", label:"<span class='webix_icon fa-user'></span> My Label" }
