jQuery UI sortable provides support for customizing the behavior of non-sortable items, as demonstrated on this page.
To designate certain items as non-sortable, simply add a special class to them using the css binding and utilize the cancel option by specifying the class name for non-sortable items.
You can further customize the sorting functionality by setting options within the sortable binding using the options parameter:
data-bind="sortable: {data: items, options: { cancel: '.no-sort' }}"
For a basic example in HTML:
<ul data-bind="sortable: {data: items, options: { cancel: '.no-sort'}}">
<li data-bind="text: name, css: { 'no-sort': disabled}"></li>
</ul>
Accompanied by the JavaScript snippet:
var vm = {
items: [
{name: 'name1', disabled: false},
{name: 'name2', disabled: false},
{name: 'name3', disabled: true},
{name: 'name4', disabled: false},
{name: 'name5', disabled: true}
]
}
ko.applyBindings(vm);
