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.
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 the layers below, you can temporarily hide it. 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:
Note: Hidden layers and groups are not included when your image is exported.
Grouping layers into layer groups lets you make your compositions more organized. It also lets you apply effects and adjustments to a number of layers together without having to merge 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:
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.
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:
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:
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:
To merge every layer in a composition:
You can add different color tags to layers to better organize multi-layered documents.
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:
To reset all filters, click Clear All.
Renaming groups and layers in the Layers list helps organize your document.
To rename a layer do one of the following:
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.
