 <p>I assume that <code>settings.widgetSelector</code> selects the top element of a widget, that is, the table or a Telerik wrapper around it. I leave your other code intact:</p> <pre><code> ... if(confirm('This widget will be removed, ok?')) { // reference to current widget wrapper var widget = $(this).parents(settings.widgetSelector); // disable and select (all) contained checkboxes widget.find('input[type=checkbox]').prop({disabled: true, checked: true});​​​​​​​​​​​​​​ // animate and remove widget... widget.animate({ opacity: 0 ... </code></pre> <p>Note that this solution will disable and select <em>all</em> contained checkboxes in a widget. If you have multiple checkboxes and only need to select a single one, give it a class (e.g. <code>myCheckbox</code>) and change the selector to</p> <pre><code> widget.find('input[type=checkbox].myCheckbox').attr({disabled: true, checked: true});​​​​​​​​​​​​​​ </code></pre> <p>You should not use the existing checkbox ID if you have more than one widget, as element IDs should be unique for the whole document.</p> <p>UPDATE:</p> <p>Turned out that I misunderstood the problem: the checkboxes to be disabled are not inside the mentioned widgets and the actual task is to </p> <blockquote> <p>…disable the input type="checkbox" if the value of the input type ="hidden" that exist in the same is equal to the id of the li (widget).</p> </blockquote> <p>(See discussion in comments.)</p> <p>This could be a solution:</p> <pre><code>... $(settings.widgetSelector, $(settings.columns)).each(function () { var widgetId = this.id; var thisWidgetSettings = iNettuts.getWidgetSettings(widgetId); if (thisWidgetSettings.removable) { $('&lt;a href="#" class="remove"&gt;CLOSE&lt;/a&gt;').mousedown(function (e) { e.stopPropagation(); }).click(function () { if(confirm('This widget will be removed, ok?')) { // Disable checkboxes which have a sibling hidden input field with value equal to widgetId $(​'table tr input[type=hidden]').filter(function() { return $(this).val()​​​​​ == widgetId; }).siblings('input[type=checkbox]').prop({disabled:true, checked: true}); // animate and remove widget... $(this).parents(settings.widgetSelector).animate({ opacity: 0 ... </code></pre>
