Question

How do I dynamically update the items in a drop down?

I have a custom plugin for CKEditor that populates a drop down menu with a list of items which I can inject into my

I could not find any helpful documenatation around richcombo, i took a look to the source code and got an idea of the events i needed.

@El Che solution helped me to get through this issue but i had another approach to the problem because i had a more complex combobox structure (search,groups)

            var _this = this;
                populateCombo.call(_this, data);

                function populateCombo(data) {
                    /* I have a search workaround added here */

                    this.startGroup('Default'); /* create default group */

                    /* add items with your logic */
                    for (var i = 0; i < data.length; i++) {
                        var dataitem = data[i];
                        this.add(dataitem.name, dataitem.description, dataitem.name);
                    }

                    /* other groups .... */
                }

                var buildListHasRunOnce = 0;
                /* triggered when combo is shown */
                editor.on("panelShow", function(){
                    if (buildListHasRunOnce) {
                        // reset list
                        populateCombo.call(_this, data);
                    }
                    buildListHasRunOnce = 1;
                });

                /* triggered when combo is hidden */
                editor.on("panelHide", function(){
                    $(_this._.list.element.$).empty();
                    _this._.items = {};
                    _this._.list._.items = {};
                });

NOTE All above code is inside addRichCombo init callback

• I remove combobox content on "panelHide" event
• I repopulate combobox on "panelShow" event

Hope this helps
