The tag can be controlled by Fields. To do so, enable the Use Fields option in the Basic Properties menu.
Selection tags have one of two states: selected or unselected. The value at which an element is seen as being selected is defined by this setting. A Tolerance value of 50% means that the value must be larger than 0.5 in order to be deemed selected. If Tolerance is set to 100%, even a value of 0.1 will be deemed selected.
See, for example: Field.
