Values: day, week, month, all (all events)
DefaultBy default the "exclude_view" is NOT enabled, therefore if you have not turned off the "show_view_menu", each of the view options will be shown. See image below.
Excluding a ViewIf you want to exclude an option from the view menu this can be done using the following widget code. In the widget example below, I am hiding the "Day" and "All Events" from appearing in the view menu. Notice that you can set multiple "exclude_view" options.
<widget type="events_calendar"> <arg id="exclude_view">day</arg> <arg id="exclude_view">all</arg> </widget>
Result: "Week" and "Month" are the only options that appear in the view menu.
