Widgets are often small, reusable pieces of content, which can be easily applied to documents throughout a project using the Apply Widget dialog. Widgets can contain any type of content, including interactions. You may save content as a widget at any point (using Document > Save As, for example), in order to easily reuse that content later in other documents.
The Apply Widget dialog can be opened using Home > Apply Widget. It allows you to search, browse, view, and apply widgets from any project to the current document. Applying a widget will insert the entire content that has been saved in the widget into your current document, without affecting pre-existing content. Any number of widgets can be applied to a document, and the same widget can be applied several times if necessary.
