Preventing items from showing in Timeline

Dear community members,

I have been experimenting with Omeka recently, specifically with the Timeline plugin. Could you please tell me how I would prevent an item from showing up in the Timeline plugin. I have 3 items created in Omeka, 2 of which are of Timeline type, and the last one is Document, still all the three items are shown in the Timeline plugin.

Thanks a lot,

I found a way of displaying the items I want by assigning them a unique tag and then submitting that tag to the get_items() function.
