In addition, if you want to separate the enum ordinal name from the string displayed in the GUI, add additional properties, for example a displayName:

public static enum State {

    OPEN("open"),
    IN_WORK("in work"),
    FINISHED("finished");

    private final String displayName;

    State(String displayName) {
        this.displayName = displayName;
    }

    public String getDisplayName() {
        return displayName;
    }
}

And in the html file:

This will present the displayName to the user and allows you to silently change this strings later without refactoring the code. You may add more properties like th:title this way.
