MultiSelectBox with Filter

[Daniel]

My project requires a MultiSelectBox.

I have found an addon build on KendoUI DropDownList widget here:
http://www.telerik.com/forums/multi-select-with-checkboxes-plugin

I have changed the code to work with KendoUI version 2015.1.429.
(I believe it works with later versions, too.)

Please see my code:
http://dojo.telerik.com/@DUKEiLL/OziqE

How can I add a filter option to this addon so it works properly?

Thank you,
Daniel.

Hello Daniel,

You could extend the initialization of the kendoMultiSelectBox with applying the filter settings. I have modified the dojo example below:

Hello Nencho,

 

Thank you for your answer.

I have tried to apply filter settings.

However, it does not work properly!

For example, using the filter causes the "Select All" option to disappear.

 

Best regards,

Daniel.

Hello Daniel,

It seems that the _addSelectAllItem function is causing the experienced problematic behavior. However, I am afraid that we do not support such custom extension of our widgets.

This is why, my suggestion would be to use the MultiSelected widget:

https://github.com/telerik/kendo-ui-core/blob/a4516594093af45b3f10fda3e08e26b5e20c2c83/docs/web/multiselect/how-to/checkbox-item-template.md

If you can still decide to go with the custom approach - I am afraid that we cannot provide you with an accurate assistance.
