javascript - how to avoid drag and drop for a specific list item in sap.m.list -

-

i have implemented drag n drop sap.m.list below. need avoid drag drop specific items of list. how stop drag n drop feature specific items

 jquery.sap.require('sap.ui.thirdparty.jqueryui.jquery-ui-core');  jquery.sap.require('sap.ui.thirdparty.jqueryui.jquery-ui-widget');    jquery.sap.require('sap.ui.thirdparty.jqueryui.jquery-ui-mouse');    jquery.sap.require('sap.ui.thirdparty.jqueryui.jquery-ui-draggable');    jquery.sap.require('sap.ui.thirdparty.jqueryui.jquery-ui-sortable');      my.clauserendering = function (ocontrol) {           //inject control             //debugger;           test = this;              test.ocontrol = ocontrol;            };            my.clauserendering.prototype = {                onafterrendering: function () {                $("#clauselist-listul").addclass('ui-sortable');                     $("#clauselist-listul").sortable({                          //connectwith : ".ui-sortable"                           cancel: '',                      start: function(event, ui) {                       debugger;                   ui.item.startpos = ui.item.index();                    },               // sync model after reordering in box                  stop: function(event, ui) {                   //debugger;                  ----                 }                       }).disableselection();             }    var clauselist=sap.ui.getcore().byid("clauselist");          clauselist.adddelegate(new my.clauserendering(clauselist));

here html view list list take tag class "ui-sortable" items in list draggable . need stop drag , drop specific items in list.

you can initialize sortable cancel option:

$(".ui-sortable").sortable(    { cancel: ".non-draggable" } );

or can set later:

$( ".ui-sortable" ).sortable( "option", "cancel", ".non-draggable" );

of course instead of "non-draggable" class can use selector
