    Hello Rhituparna,

    I am not exactly sure what is causing this. Here is a simple Dojo demo, which shows how cascading multiselects could be implemented. I would suggest you modify it in order to replicate the erroneous behavior. Thus we will be able to observe the problem locally and advice you further.

    Hello Georgi,

    My problem is that the multiselect list I am using has dependency.Like,you have given me an example of two multiselect lists.One for Supplier and another for products.In my case,I have one dropdown for supplier and another multiselect list for products.For each Supplier I have different products.But when ,I am changing the supplier I am having multiple lists there in products.There is a problem of caching data.The old list is remaining along with the new one.I want my multiselect list to be refreshed each time when I change supplier in the dropdownlist.

    Hello Rhituparna,

    The demo I've referenced uses serverFiltering set to true, which means that widget will show the date returned from the server. It will not cache neither combine it with the current one.
    If you are experiencing any cache issues, I would suggest you check the server response and verify that it returns the correct result data.
