Switch widget hides all subelements whose label do not match given
variable current value representation. For exemple if given variable type
is HMI_INT and value is 1, then elements with label '1' will be displayed.
Label can have comments, so '1#some comment' would also match. If matching
variable of type HMI_STRING, then double quotes must be used. For exemple,
'"hello"' or '"hello"#another comment' match HMI_STRING 'hello'.
