javascript - How to control the movement of search box while searching any element in it? -


i have made search box , whenever search element in it, search box moves towards right reasons. here fiddle it.

i want make sure, whenever searching element, box should not move (not going towards right or left).

the html, css , js have used form are:

   function myfunction() {              var input, filter, ul, li, a, i;              input = document.getelementbyid("myinput");              filter = input.value.touppercase();              ul = document.getelementbyid("myul");              li = ul.getelementsbytagname("li");              (i = 0; < li.length; i++) {                  = li[i].getelementsbytagname("a")[0];                  if (a.innerhtml.touppercase().indexof(filter) > -1) {                      li[i].style.display = "";                  } else {                      li[i].style.display = "none";                        }              }          }
   /* search box start */            #myinput {          background-image: url(../assets/img/uploads/searchicon.png);          background-position: 99% 50%;          background-repeat: no-repeat;          font-size: 16px;          margin-top: 100px;          width: 670px;          margin-right: auto;          display: block;          margin-left: auto;          padding: 12px 20px 12px 40px;          border: 1px solid #ddd;          margin-bottom: 12px;      }                  /* search box finish */                  /* search box dropdown start */            #myul {          list-style-type: none;          padding: 0;          width: 670px;          margin-bottom: 200px;          margin-left: auto;          margin-right: auto;      }            #myul li {          border: 1px solid #ddd;          margin-top: -1px;          /* prevent double borders */          background-color: #f6f6f6;          padding: 12px;          text-decoration: none;          font-size: 18px;          color: black;          display: block      }            #myul li a.header {          background-color: #e2e2e2;          cursor: default;      }            #myul li a:hover:not(.header) {          background-color: #eee;      }
<input type="text" id="myinput" onkeyup="myfunction()" placeholder="search.." title="type in name">                <ul id="myul">              <li><a href="#" class="header">a</a></li>              <li><a href="#">b</a></li>              <li><a href="#">c</a></li>                    <li><a href="#" class="header">d</a></li>              <li><a href="#">e</a></li>              <li><a href="#">f</a></li>                    <li><a href="#" class="header">g</a></li>              <li><a href="#">h</a></li>              <li><a href="#">i</a></li>              <li><a href="#">j</a></li>          </ul>

it's caused because of elements overflow screen's height causing scrollbar appear, if want have "fullscreen", can work way around css:

body {overflow: hidden;}

or have less results showing when in initial state.
