Layers panel
The 
Layers panel provides quick access to layers, layer configurations, and tools for creating and deleting layers.
The image below shows an example of the Layers panel of a layered PDF:
Layers with child layers will have a toggle triangle to the left of their names. Click this triangle to expand or collapse the list of child layers.
Go to Window > Panels > Layers or press ALT+Y to show the Layers panel.
Show or hide layersTo show or hide a layer, select the box to the left of the layer's name to toggle its visibility. A layer with an 
eye icon in the box is visible and a layer with an empty box is hidden.
To show or hide a parent layer and all its child layers at the same time, right-click the parent layer and select Show Layer. This toggles the show/hide setting of both the parent layer and all child layers.
To show only one layer, right-click the layer name and select Isolate. The selected layer and its children will be shown and all other layers will be hidden.
See Using Layer Visibility for more information.
Move layersDrag a layer to move it to a new location in the layers list. A small triangle will appear to show where the layer will be located when you release it. Move the cursor to the right to make the layer a child of the layer above the cursor.

- Select: Scrolls through layers without changing the view. Press the Surface Dial to select the current layer, either hiding or showing it depending on its current state.
Add New Layer: Adds a new, blank layer to the PDF. The location of the new layer depends on the option selected from the menu.
- Add Before: Creates a new layer before the selected layer. If no layer is selected, the new layer is added to the top of the layers list.
- Add After: Creates a new layer after the selected layer (default). If no layer is selected, the new layer is added to the bottom of the layers list.
- Add Child: Creates a new layer as a child of the selected layer. If no layer is selected, this option is not available.
Add Layer from Page: Adds a layer to the PDF from the content of a source PDF. The location of the new layer depends on the option selected from the menu.
- Add Before: Creates a new layer before the selected layer. If no layer is selected, the new layer is added to the top of the layers list.
- Add After: Creates a new layer after the selected layer (default). If no layer is selected, the new layer is added to the bottom of the layers list.
- Add Child: Creates a new layer as a child of the selected layer. If no layer is selected, this option is not available.

Add Layer from Page button.

Print: Sets whether a layer will be included in when the PDF is printed.
Export: Sets whether a layer will be included in an export when using Export Layer to Page.
Zoom: Sets whether the contents of a layer are always visible or are only visible when the user zooms in (or out) within a defined range. To enable, select On when in range and then define a zoom range. The contents of this layer will only appear when the display zoom is within this range.
