Hide Empty Tags #33

Closed stardisblue closed 9 years ago

stardisblue commented 10 years ago

Hello,

What can i do to hide an empty tag, It's for multiple selection, for exemple. When i select Genre : action what i need to do with the empty tags in the actor category. I guess it's not so difficult, just need to hide the tags with count 0.

Thank you. Sorry if my english is bad, i'm french.

replace rewriteFields:

    Filtrify.prototype.rewriteFields = function () {
        var field;
        for ( field in this._fields ) {
            this._menu[field].tags
                .children()
                .each( this._bind( function( index, element ) {
                    var tag = ( element.textContent || element.innerText ),
                        count = this._fields[field][tag] === undefined ? 0 : this._fields[field][tag];

                    element.setAttribute("data-count", count );

                        if ( count === 0 ) {
                            $(element).addClass("ft-no-items-hidden");
                        } else {
                            $(element).removeClass("ft-no-items-hidden");
                        };  
                }, this ) );
        };
    };

and .ft-hidden

.ft-hidden, .ft-no-items-hidden { display: none !important; }
