We have some great news for you! Webix was updated to the version 2.4 which includes such great enhancements as a new Portlet widget, MultiCombo and Range Slider form controls, naming only the smallest part of all the changes.

Portlet widget

Portlet is a layout component that can include another component inside of it. Moreover, it’s possible to re-order portlets by drag-and-dropping them in the necessary position on your web page.

Therefore, you shouldn’t write lines of code to change the arrangement of your web page. All that you need is to grab a portlet by the handler with an inserted widget and put it at the place of future drop which is highlighted by a specific color. Want to check its performance? View this demo.
