Use K2 Workspace to review and respond to K2 tasks, access workflow and form data, review progress using reports, and manage your login and out of office settings.
You can access the workspace by launching a web browser and navigating to the workspace site URL, e.g. https://{k2server}/workspace , where {k2server} is the name of your K2 application server, its network alias, or the name of the server where the K2 web components have been installed. Check with your K2 administrator if you are not sure what the {k2server} value is for your environment.
Click Process Overview to view the details and status of workflows that you have rights to view, or click My Overview to view reports for workflows in which you have participated.
The list allows you to navigate to other workspaces and sites. Use the app links to navigate to otherworkspacesand other sites, such asK2 ManagementandK2 Designer. These menu items are available if you have permissions to access the other apps and workspaces.
The K2 Designer link will only show in the app list if you are a member of the Designer role.
Using the Left Pane
Clicking on the My Tasks or My Forms links collapses the menu to the left and shows an icon-only view. You can still access items and menus in the collapsed state. Click the home or report icons to expand the pane.
Clicking on tasks or forms does not collapse the entire menu, just the main menu to show list of tasks in submenu. What I need is to be able to collapse main menu, free some screen space regardless of which menu item is active like in this screenshot
