jQuery drag and drop expands -


what want drag cube on box. box expands , cube can placed on 1 of 3 'timelines'.

my html: 

<div class="drag"></div> <div class="addroom one">     <div class="timeline">         <div id="t1"></div>         <div id="t2"></div>         <div id="t3"></div>     </div> </div> <div class="addroom two">     <div class="timeline">         <div id="t1"></div>         <div id="t2"></div>         <div id="t3"></div>     </div> </div>

my javascript:

$(function () {     $(".drag").draggable({         revert: "invalid",         snap: '#t3, #t2, #t1',         snapmode: 'inner'     });     $(".timeline").droppable({         over: function (event, ui) {             $(this).css('height', "66px");             $(".timeline #t1").droppable({});             $(".timeline #t2").droppable({});             $(".timeline #t3").droppable({});         },         out: function (event, ui) {             $(this).css('height', "24px");         },         drop: function (event, ui) {             $(this).css('height', "24px");         }     }); });

jsfiddle: http://jsfiddle.net/h7xv9/

as can see possible drop on t1, t2 , t3.but want t2 , t3 droppable when timeline expanded!

use:

overflow:hidden

on t2 , t3

jsfiddle

also, converted them class rather id. it's illegal have multiple ids in real world, should illegal in html too.

update ops comments

markup

to each t# class added drop class

<div class="drag"></div> <div class="addroom one">     <div class="timeline">         <div class="drop t1"></div>         <div class="drop t2"></div>         <div class="drop t3"></div>     </div> </div> <div class="addroom two">     <div class="timeline">         <div class="drop t1"></div>         <div class="drop t2"></div>         <div class="drop t3"></div>     </div> </div>

javascript

$(function () {     $(".drag").draggable({         revert: "invalid",         snap: '.t3, .t2, .t1',         snapmode: 'inner'     });     $(".drop").droppable({ // assign event drop class         over: function (event, ui) {             $(this).parent().css('height', "66px");         },         out: function (event, ui) {             $(this).parent().css('height', "24px");         },         drop: function (event, ui) {             $(this).parent().css('height', "24px");         }     }); });
