User interface hooks allow you to add snippets of HTML-encoded text to WorldServer pages. For example, if you wanted to display additional information above the task list on Task List for Project page, use UIHooks in to specify a file that contains the desired text and other hook-specific information.
WorldServer displays the Add Custom UI Hooks Component dialog.
The Choose file dialog box closes and the selected file is listed in the Add Custom UI Hooks Component dialog.
WorldServer returns to the refreshed Customization page.
