New to Flux 3 is the Widget Gallery, which is a collection of pre-configured widgets that can be placed into your web pages.
Although most of the widgets come pre-configured, they are simply HTML, JavaScript and CSS, so can be modified just like you had created them from scratch.
To insert a widget, first select the widget you want to insert in the list in Widgets section of the Actions & Widgets palette.
Once you have selected the widget, select the element on your page to insert the widget into, this will usually be a DIV element, and press the Insert button on the palette.
When you press the Insert button, a dialog will appear to allow you to setup the widget, the recommended settings will be pre-selected, so you can usually just press Insert....
Many widgets require an ID, so type in a unique name if the Widget ID field is enabled.
