How to handle data from different html lists?

Posted: Tue Mar 23, 2010 4:17 am

Hi.
I have the code where I can drag and drop items to the 5 different html lists.

When I have dragged items to the lists I would like to save the result.
So my problem is that when I save the result I don't know where from the lists data comes.

Could you please help me if you understand what I mean?

The code is following:

body,html {
color:#333;
font-family:Calibri;
font-size:11px;
}
.panel {float:left;width:200px;margin:20px;}

ul {
list-style-type:none;
border:1px solid #999;
background:#ccc;
padding:20px;
min-height:150px;
width:100px;
}

li {
display:block;
border:1px solid #999;
background:#fff;
width:80px;
padding:5px 10px;
margin-bottom:5px;
}

.dds_selected {
background:#ffc;
}
.dds_ghost {
opacity:0.5;
}
.dds_move {
background:#cfc;
}
.dds_hover {
background:#fc9;
border:3px dashed #c96;
}

.holder {
border:3px dashed #333;
background:#fff;
}

</style>

Re: How to handle data from different html lists?

Some more info :)

The point is that I would like to know that where of the 5 ul lists each of the names (Investments, Family, Sport, Friends, Age, Skills) has been dragged.

Like:

list_1 contains: Investments, Sport
list_2 contains: Family
list_3 contains: Skills
list_4 contains: -
list_5 contains: Friends, Age

Hope you will understand better :)
