Image Selector
From WikiFour51
Contents |
Overview
This widget creates a thumbnail and preview image selection interface. When the image selector is defined the spec control is replaced with a scrolling thumbnail preview of all images and a larger preview when an image is selected. This is designed to provide an enhanced user input for image choices you make available in your Pageflex project. Events are exposed that allow you to write code against the widget. Custom parameters are available to alter the styling of the control.
Instructions
HTML tag must be created that will contain the spec control token. Within the Advanced Scripting tab you must attach the widget to the spec control. In the attachment you may specify optional parameters that define the rendering of the control.
