I want to use the field: "product" to be a selection menu using the visualize feature "control".
Data of field: "product" contains three types: keyboard, computer, screen.
In default "control" function, my select menu will show these three types keyboard, computer, screen.
Is there a filtering function to make my menu only show two types: keyboard, computer ?
In the "Line" visualize, it support us to use KQL section to filter data, however, it doesn't appear in "Control" visualize.
