Using Flash Components in Visual Composer Models 
You can integrate Flash files created externally into Visual Composer models, so that they can be selected when you drag a Flash view icon from the Compose task panel as Flash components.
You have created a Flash-compatible component and packaged its files in a single ZIP file.
You have uploaded the component to the Visual Composer server, as follows:
In Storyboard, choose . The Flash Component Manager dialog box is displayed.
Click Upload. The Upload New Component field is activated at the right.
Click Browse and locate the ZIP file that you want to upload.
Click Upload. The system evaluates the ZIP file to ensure that the structure and contents are valid for the Flash component. Upon successful upload, the component is displayed (name and icon) in the left pane.
Drag the Flash view icon onto the Design board. The Select a Flash Component dialog box is displayed.
From the list of available Flash components in the left pane, select the item that you need and click OK. The component is added to your model.
Switch to the Configure task panel to select the attributes for the newly-added Flash component. You can configure the name (Flash view title) of the component, its Frame style and its Visibility condition.
You can define the input and output to/from the element as you would any other model component.
