The resulting window, **Filter Attributes** is described below.

Filtering limits the attributes displayed in the long list on the
left, allowing you to more easily find attributes of interest.

**Passing** : indicates the number of attributes passing the filters out of the
total number attributes. These numbers also appear in the main window header to
the right of the filter button.

**Values** : allows you to limit the list to those attributes with values of the
data types checked. More information on attribute data types may be found at
:doc:`dataTypes` .

**Tags** : allows you to limit the list to those attributes with the tags checked.
Not all maps have tags. Note that tags are not mutually exclusive; if an
attribute has more than one tag and any of its tags are checked, that attribute
will appear in the list.

The filter icon will be orange |orange| if any filters are affecting the attributes
displayed in the long list on the left.
