Following is the change which I made in the refiner’s display template.

Actual code

<option value='_#= onChangeOrClick =#_'>_#= $htmlEncode(refinementName) =#_</option>

 Updated Code

<option value='_#= onChangeOrClick =#_'>_#= $htmlEncode(refinementName)  =#_  (_#= refinementCount =#_)</option>

The post Add count to drop down refiners in SharePoint search refinement webpart appeared first on Binary Bits.

The “Available Refiners” is available in “Drop Down” type refinement panel.

When the refinement panel is being loaded, SharePoint executes a JavaScript function named AddPostRenderCallback. This would be available in the Refinement Display Template located under MasterPage/Search Gallery. The actual method looks like below code which is taken from O365.

AddPostRenderCallback(ctx, function() {
    if (hasAnyFiltertokens) {
        // Get the hidden block
        var hiddenOptions = document.getElementById(hiddenBlockID).children;
        var unSelGroup = document.getElementById(unselDD);
        var selGroup = document.getElementById(selDD);
        // Clone all the elements from the hidden list to the unselected option group
        for (var i = 0; i < hiddenOptions.length; i++) {
            var selectedElm = GetAllElementsWithAttribute(selGroup, 'value', hiddenOptions[i].getAttribute('value').replace('updateRefinersJSON', 'removeRefinementFiltersJSON'));
            if (selectedElm === null || selectedElm.length <= 0) {
                var cloneElm = hiddenOptions[i].cloneNode(true);
                unSelGroup.appendChild(cloneElm);
            }
        }
    }
});

To the above original code I made a small change so that “Clone all the elements” code executes only when user has selected a refiner.

// Clone all the elements from the hidden list to the unselected option group
if(selectedFilters.length <= 0)
{
	for (var i = 0; i < hiddenOptions.length; i++) {
		var selectedElm = GetAllElementsWithAttribute(selGroup, 'value', hiddenOptions[i].getAttribute('value').replace('updateRefinersJSON', 'removeRefinementFiltersJSON'));
		if (selectedElm === null || selectedElm.length <= 0) {
			var cloneElm = hiddenOptions[i].cloneNode(true);
			unSelGroup.appendChild(cloneElm);
		}
	}
}

To the above orignal code I added the following code to hide the “Available Refiners” option.

if(selectedFilters.length > 0)
{
	if(unSelGroup!=null)
	{
		unSelGroup.style.display = 'none';
	}
}

The above code will hide the “unSelGroup”‘s “Option Group” HTML to hide the Options for “Available Refiners”.

Final code would look like below.

AddPostRenderCallback(ctx, function() {
    if (hasAnyFiltertokens) {
        // Get the hidden block
        var hiddenOptions = document.getElementById(hiddenBlockID).children;
        var unSelGroup = document.getElementById(unselDD);
        var selGroup = document.getElementById(selDD);
        // Clone all the elements from the hidden list to the unselected option group
        if(selectedFilters.length <= 0)
        {
            for (var i = 0; i < hiddenOptions.length; i++) {
                var selectedElm = GetAllElementsWithAttribute(selGroup, 'value', hiddenOptions[i].getAttribute('value').replace('updateRefinersJSON', 'removeRefinementFiltersJSON'));
                if (selectedElm === null || selectedElm.length <= 0) {
                    var cloneElm = hiddenOptions[i].cloneNode(true);
                    unSelGroup.appendChild(cloneElm);
                }
            }
        }
        //Added for Gold Asset requirement where once a refiner is selected the "Avaialble Refiners" item should be made hidden
        if(selectedFilters.length > 0)
        {
            if(unSelGroup!=null)
            {
                unSelGroup.style.display = 'none';
            }
        }
        
        var refinerUpArrow = document.getElementById('refinerExpandCollapseArrow');
        if(refinerUpArrow!=null)
        {
            refinerUpArrow.style.display = 'none';
        }
        
    }
});

End Result is following
