Hi Roger, - - To achieve the desired appearance I would suggest you to add a click event handler to the arrow button. When the arrow is clicked and the popup for filtering appears, you could find all the checkboxes through the '.k-checkbox' class. Then for each checkbox, if it is checked, you could hide the respective item. Note, that you will need to exclude the checkbox corresponding to the 'All' node (marked in orange below). In order to ensure, that the checkboxes are rendered by the time you are trying to check their values, you will need to use setTimeout function. - - - $('.k-icon.k-i-arrow-60-down').click(function(){ - - setTimeout(function(){ - var checkboxes = $('.k-checkbox'); - for(var p=0; p - var checked = checkboxes[p].checked; - if(!checked){ - $(checkboxes[p]).closest('.k-item').not('.k-first').hide() - } - } - }, 0) - }) - - - Here you will find a Dojo example, where the approach described above is implemented. - I hope this helps. - - Regards, - Neli - Progress Telerik - - Try our brand new, jQuery-free Angular components built from ground-up which - deliver the business app essential building blocks - a grid component, - data visualization (charts) and form elements. -

Hi Roger,

To achieve the desired appearance I would suggest you to add a click event handler to the arrow button. When the arrow is clicked and the popup for filtering appears, you could find all the checkboxes through the '.k-checkbox' class. Then for each checkbox, if it is checked, you could hide the respective item. Note, that you will need to exclude the checkbox corresponding to the 'All' node (marked in orange below). In order to ensure, that the checkboxes are rendered by the time you are trying to check their values, you will need to use setTimeout function.

$('.k-icon.k-i-arrow-60-down').click(function(){



    setTimeout(function(){

        var checkboxes = $('.k-checkbox');

        for(var p=0; p < checkboxes.length; p++){

            var checked = checkboxes[p].checked;

            if(!checked){

                $(checkboxes[p]).closest('.k-item').not('.k-first').hide()

            }

        }

    }, 0)

})

Here you will find a Dojo example, where the approach described above is implemented.
I hope this helps.
