Expand and Collapse buttons can be implemented on views to manage categorized documents (see Figure 14.2). When implemented on views, all view categories are expanded or collapsed similarly to sections on a documentas illustrated in the previous section. These buttons provide a user-friendly method to manage the display of information.
Figure 14.2. Categorized view with Expand and Collapse buttons
How It Works
Sections are expanded and collapsed using the built-in Formula Language commands ViewCollapseAll and ViewExpandAll. These commands are typically added to action buttons. When users click the button, all sections on the document expand or collapse. If there are no sections on the view, the buttons will have no effect when clicked.
To implement this solution, create two action buttons called Expand and Collapse on the view. Insert the following formula to collapse the sections.
Insert this formula to expand all sections on a view.
