Add a layer

Layers group similar types of events together on your timeline.

For example, in a timeline about your life, you might have a layer for places you've lived, another for places you've worked, and another for your relationships.

Add a new layer

When you create a timeline, all events go in the same layer, called "Events". Preceden doesn't display this default layer's name on your timeline:

A timeline whose only layer is the unnamed default one, holding a single New York City event spanning 2012 to 2017

To add a layer, click the Add Layer button above your timeline.

Name is the only required field.

The Add Layer dialog, with a required Name field, a Notes field, and collapsed Layer Order, Content Visibility and Color sections

You can also:

Add layer notes
Change the layer order if there are multiple layers in your timeline
Hide the layer
Set a color for the layer

Let's add a layer called "Places I've Worked":

The same timeline after a second layer is added: the New York City event sits in the Events layer and the new, empty Places I've Worked layer appears below it

Now that there are two layers, the default layer's name ("Events") appears on the timeline.

The timeline with the default layer's name, Events, highlighted now that a second layer makes it visible

You can rename it by clicking the layer name on the timeline, or its name in the list below the timeline. Let's change it to "Places I've Lived".

With more than one layer on your timeline, each event gets a Layer menu for choosing which layer it belongs to:

The Update Event dialog for a Microsoft event, with the Layer menu highlighted and set to Places I've worked

The new event is in the "Places I've Worked" layer, so it is grouped separately from the events in the "Places I've Lived" layer:

The finished timeline with New York City in the Places I've Lived layer and Microsoft in the Places I've Worked layer below it
