php - anchor tag doesn't work through a different page -

i have built site using foundation , php. on index.html using foundation scroll feature scroll different sections of page.

on php page wanted set navigation links links respective section on index.html , thought easy using anchor tags. out links first(#second) links through correctly, rest go straight bottom of index.html page.

i have been searching , can't find why 1 work , not others, there missing? here code

//code

//target section in index.html      <div class="row">         <div class="large-8 column large-centered" id="third" data-magellan-target="third">             <h2 class="heading">location</h2>             <div class="border">                 <div id="map">                     <!--map location-->                 </div>             </div>          </div>     </div>   //navigation on php page                  <div class="top-bar-right">                     <ul class="menu vertical medium-horizontal nav" data-responsive-menu="drilldown medium-dropdown" data-magellan>                         <li><a href="index.html">home</a></li>                         <li><a href="#">sales</a></li>                         <li><a href="#">lettings</a></li>                         <li><a href="index.html#second">gallery</a></li>                         <li><a href="index.html#third">location</a></li>                         <li><a href="index.html#fourth">contact us</a></li>                     </ul>                 </div>

//edit//

i found issue, jquery plugin had installed conflicted magellan feature, once removed worked correctly.

your page may not long enough achieve desired result; anchor tags not make whatever link absolute top item on page instead respect page boundaries (you don't have enough material below tags before hitting bottom of page). guess if added few hundred empty p-tags

<p></p> 

to bottom of index.html , tried again you'd desired response (this test, not solution). may want consider drawers (hide/show) alternative.
