The Filter provides options for defining the text of its filter operators (for example, contains, equals, or greater than) and logic messages (for example, AND and OR).

To localize the messages, set the desired strings in the messages field. To localize the names of the operators, list the available ones and set their text in the operators field.

<div id="filter"></div>
<ul id="listView"></ul>

<script type="text/x-kendo-template" id="item">
        <strong>#= name #</strong>, aged #= age #, is on vacation: #= isOnLeave #
