Hi i want to make an animation menu and i have a problem: when i hover the submenu buttons they dissapear.

pag=submenu photo id
inceput= submenu buttons id


so here's the code:

$(document).ready(function () {
  $("#m1").hover(function(){
    $("#pag").stop().animate(
      {width:"450px"},
      {duration:500})
      $('#inceput').show("normal");
    },function(){
    $("#pag").stop().animate(
      {width:"0px"},
      {duration:500})
$('#inceput').hide("normal");     })
        

        $('#pag').hover(
            function() {
               
    $("#pag").stop().animate(
      {width:"450px"},
      {duration:500})
 },
            function() {
