I want to using multi-select in spreadsheet validation custom

[Duc Thuan]

In demo https://demos.telerik.com/kendo-ui/spreadsheet/custom-editors

cells: [

   { value: "Select item:", bold: true },

   { background: "#fef0cd",

   validation:{

       dataType: "list",

       showButton: true,

       comparerType: "list",

       from: '{ "Foo item 1", "Bar item 2", "Baz item 3" }',

       allowNulls: true,

       type: "reject"}

    }]

I need to choose multi item.

How do i fix it?

Thanks !

Hello,

I have replied in the other thread you have opened about the same topic. For convenience I will post my reply here as well. I would suggest you to keep the conversation in a single thread. 

You can use the approach described in the following Forum thread and place a MultiSelect widget instead of the DropDownList.
Here is a Dojo example where such scenario is demonstrated.

Hi Duc Thuan,

In case, when you have duplicated a ticket by mistake, you could mark one of the threads as 'Client Close Request'. Thus, one of the threads will be closed and all the replies concerning the topic will be in a single thread. This way will be much more easier for the other users who are searching for information on similar issues.
