Organize and manage layers
When working in more complex compositions with a large number of layers, you can use the various layer management tools to make it easier to keep track of all the layers in your image. For example, you can group certain layers together, hide them if you don’t currently need to see or edit them, or lock them if you’d like to keep them visible but prevent them from being edited. You can also name layers, merge layers, and more.
Hide or show a layer or layer group
In the Layers list, you can disable layers and groups to make them invisible in the canvas without removing them from your composition. For example, if a large image layer obstructs other layers you want to adjust in the canvas, you can temporarily hide the offending layer. If you hide a group, you also hide all layers and groups nested in it. However, hidden layers and groups can still be deleted, renamed, and rearranged in the Layers sidebar.
Select the layers you'd like to hide or reveal.
Do one of the following:
- Choose Arrange > Hide or Arrange > Show (from the Arrange menu at the top of your screen).
- Press + on your keyboard.
- In the Layers sidebar (choose View > Layers > Show Layers if the list view isn’t visible), move the mouse pointer over the layer or layer group you’d like to hide or show and click the visibility icon
.
- In the Layers sidebar, –click a layer or group and choose Hide or Show.
Note: Hidden layers and groups are not included when your image is exported.
Group or ungroup layers
Grouping layers into layer groups lets you make your compositions more organized. You can also give layer groups names to make it easier to keep track of them. When you move or resize a layer group, each layer is moved and resized together, in proportion. You can also group layers within layer groups to create nested groups.
To group multiple layers into a layer group or to ungroup them:
- Select the layers you'd like to group or ungroup.
- Do one of the following:
- Choose Arrange > Group or Arrange > Ungroup (from the Arrange menu at the top of your screen).
- In the Layers sidebar, –click the layers you’d like to group or ungroup and choose Group or Ungroup (choose View > Layers > List or View > Layers > Thumbnails if the Layers sidebar isn’t visible).
- Press + on your keyboard to group, or + + to ungroup layers.
Add layers to a layer group
Do one of the following:
Select a layer inside an expanded layer group in the Layers sidebar (choose View > Layers > Show Layers if the Layers sidebar isn’t visible) and choose one of the options from the Insert menu at the top of your screen.
Drag a layer to the layer group in the Layers sidebar.
Drag a layer group into another layer group. The group, together with all its layers, will be nested inside the layer group.
Expand or collapse a layer group
To expand or collapse a single layer group:
In the Layers sidebar, click the disclosure triangle next to the layer group's name.
To expand or collapse a layer group and all the groups nested within it:
- In the Layers sidebar, –click the disclosure triangle next to the layer group's name.
Lock and unlock layers or layer groups
When you lock a layer or layer group, it stays visible in your image but it will no longer be editable. However, locked layers and groups can still be deleted, renamed, and rearranged in the Layers sidebar.
To lock or unlock a layer or layer group, do one of the following:
- Choose Arrange > Lock or Arrange > Unlock (from the Arrange menu at the top of your screen).
- In the list Layers sidebar (choose View > Layers > Show List if the list view isn’t visible), move the mouse pointer over the layer or layer group you’d like to lock and click
.
To unlock layers, click 
. - In the Layers sidebar (choose View > Layers > Thumbnails or View > Layers > List if the Layers sidebar isn’t visible), –click a layer or layer group choose Lock or Unlock.
Merge multiple layers into a single layer
Merging (also called flattening) layers is a destructive action that combines a number of different layers into one. Any adjustments, effects, styles, or other formatting information are also flattened down into the image, so they will no longer be editable. Merging layers can be useful when you have a large image with many different layers that you won’t necessarily need to edit in the future and you want to make the image more manageable.
To merge two or more layers, do the following:
Select the layers you’d like to merge.
Then, do one of the following:
- Choose Arrange > Merge (from the Arrange menu at the top of your screen).
- In the Layers sidebar (choose View > Layers > List or View > Layers > Thumbnails if the Layers sidebar isn’t visible), –click the layer you’d like to merge and choose Merge.
- Press + + on your keyboard.
To merge every layer in a composition:
- Choose Arrange > Merge All (from the Arrange menu at the top of your screen).
- Press + + + on your keyboard.
Organize layers using color tags
You can add different color tags to layers to better organize multi-layered documents.
- To add a color tag, –click a layer and in the Tags section, pick a color.
Filter layers based on the layer type, color tag, or name
You can use the layer filtering option to quickly view all group layers, image layers, shapes, or text in a document, or filter layers by their name or the assigned color tags.
To filter layers do one of the following:
- At the bottom of the Layers sidebar, start typing the layer name into the search field.
- Click Filter
at the bottom of the Layers sidebar and pick the desired option.
To reset all filters, click Clear All.
Rename a layer
Renaming groups and layers in the Layers list helps organize your document.
To rename a layer do one of the following:
- In the Layers sidebar, double-click the layer name you want to change and type in a new name.
- In the Layers sidebar, Force click the layer name and type in a new one.
Also, if a layer has been named automatically, you can –click the layer in the layers sidebar, choose Suggested Names and pick a name from the list of suggested names.
