Hi,

I am using below code to enable checkboxes in dropdownlist.

$(“#testScenario”).jqxDropDownList({ selectedIndex: 1, checkboxes: true, source: sourceData, width: 200, height: 25});

And working good. Do we have any option here like ‘Select All’ to check all the checkboxees here ?

Thanks,
dineshnk

Thanks for reply Nadezhda.

I have already seen this one.But I mean to say that can we have select all option along-with the checkboxes option inside dropdown options?

Thanks,
Dineshnk
