It works thanks Sam

                    // moved to here and changed return
    		if (this.config.hideWhenEmpty && this.tasks.items.length === 0) {
                        this.hide()  // added hide to hide header too
    			return wrapper;
    		}

u can explain me how it works with self.hide()? where I have to write it down and so on?

do, could do self.hide()
I was returning an empty div

I think this don’t work because I see still the header. it es possible to display a empty wrapper?

	getDom: function () {
	
		//Add a new div to be able to display the update time alone after all the task
		var wrapper = document.createElement("div");

		//display "loading..." if not loaded
		if (!this.loaded) {
			wrapper.innerHTML = "Loading...";
			wrapper.className = "dimmed light small";
			return wrapper;
		}
                // moved to here and changed return
		if (this.config.hideWhenEmpty && this.tasks.items.length === 0) {
			return wrapper;
		}

For example i try this?

return this.hide()

U think it will be better?
