引導 - 保持div固定在水平滾動滾動

我有一些控制在div的底部。我希望這些控件在用戶滾動時保持固定。引導 - 保持div固定在水平滾動滾動

我嘗試： 1）使DIV固定。問題在於，該id會破壞我的引導屬性，也是因爲高度是動態生成的。

<div id="timelineContainer"> 
    <p class="mes">{{mes1}}</p> 
    <div id='chart_div' class="chart"></div> 

    <div class="row fixedcontrols"> 

    <div class="fixed col-md-1 col-lg-1 col-xs-1 form-group-lg"> 
     <button type="button" id="next1" class="btn btn-primary btn-block transback " ng-click="timeline.getPreviousData();"class="btn btn-default" data-toggle="tooltip" data-placement="top" title="Load previous 100 records..."> 
     <span id="nextdata1" class="glyphicon glyphicon-arrow-left"></span></button> 
    </div> 

    <div class="col-md-3 col-lg-3 col-xs-3 "> 
     <button type="button" class="btn btn-warning btn-block" class="tt" id="btn_ZoomIn" name="btn_ZoomIn" ng-click="timeline.zoomIn()"><span id="zoomin" class="glyphicon glyphicon-zoom-in"></span> 
     </button> 
    </div> 

    <div class="col-md-3 col-lg-3 col-xs-3 form-group-lg"> 
    <button type="button" class="btn btn-primary btn-block" id="btn_ZoomOut" name ="btn_ZoomOut" ng-click="timeline.zoomOut()"> <span id="zoomout" class="glyphicon glyphicon-zoom-out"></span></button> 
</div> 

    <div class="col-md-4 col-lg-4 col-xs-4 col-sm-4 form-group-md ff"> 
    <button type="button" id="advanced1" ng-click="timeline.searchclick()" class="btn btn-default btn-block">Show Search</button> 
    </div> 
    <div class="col-md-1 col-lg-1 col-xs-1 form-group-lg pull-right"> 
    <button type="button" id="next" class="btn btn-primary btn-block " ng-click="timeline.getNextData();"class="btn btn-default" data-toggle="tooltip" data-placement="top" title="Load next 100 records..."> <span id="nextdata" class="glyphicon glyphicon-arrow-right"></span> 
    </button> 
    </div> 

    </div> 
</div> 



#timelineContainer { 

overflow-x: scroll; 
overflow-y: scroll; 
white-space: nowrap; border: 13px solid #bed5cd; 
width: 100%; 
margin: 0 auto; 
position: relative; 
background-color: #5bc0de; 
    }

謝謝。

更新：控件在用戶滾動時移動，如下所示。我希望他們得到修復。
