<!-- how to use G_mapper -->

<!-- 1) add an input field with this structure -->
<input type="text" id="any_id_u_like" data-gmapper-input>

<!-- 2) add a div with “data-gmapper-render-for” with the id of input you've added as data attribute value -->
<div data-gmapper-render-for="any_id_u_like">

<!-- 3) add a child div with id “distance” -->
<!-- and “data-gmapper-endpoint”  with the address you want the itinerary from as value -->
