width: 50px, etc.

As it turns out, if you give the list a height and width then you can drop on it when it's empty. You can do that with standard css, ala
ul.sortable-list {
width = 100px;
min-height = 50px;
}
Thank you for your response.
I think you also have to have the sortable's dropOnEmpty parameter set to true.
There's an example on the Scriptaculous site that has this working with the code.On 3/31/06, Bryan Buchs <[EMAIL PROTECTED] > wrote:I ran into this issue too. My solution was to add an "onUpdate" function to
the sortable that tests the container to see if it's got any children or
not:
function is_empty(container)
{
if ($(container).hasChildNodes()) {
Element.removeClassName($(container),'empty');
} else if (!$(container).hasChildNodes()) {
Element.addClassName($(container),'empty');
}
}
I was using this for 2 sortable (UL) lists - my class for the "empty"
sortable just padded the container:
.empty {
padding: 10px;
border: 1px dashed #FFDD44;
background-color: #FFFF99;
}
The padding and style was enough to give a visible "target" for the users to
drop on.
