I have a team site with few subsites. Subsites are the projects that can be added at any time using template.
Every subsite has a task list.
Is there a way to setup a main task list on a root page that collects and marges all tasks from subsites, including the one created after the root site was setup?
I would like it to be displayed in a form of calendar or regular task timeline.
I have tried to use Content Search Web Part but it displays links and I would preferred to have it in a form of calendar or timeline.
I am new to sharepoint so I am not to sure if that is how it was designed to work. I would appreciate any info, including links to resources(tutorials, informations) that would help me to setup what I have described.
