Understanding the Layers Panel
the Layers panel, you can control elements of an Illustrator design by
assigning separate layers to each individual object. A top-level layer
appears at the top of the Layers panel, which indicates the top of the
stacking order. You can create layers and sublayers (nested layers)
within a top-level layer. The current layer in the Layers panel appears
with a black triangle in the upper right corner of the layer. The circle
icon on the right is the target, which you can use to apply and edit
appearances. A small square next to the target indicates an object
selection. The arrowhead next to a layer thumbnail allows you to
expand/collapse a layer group. To access the Layers panel, select the
Layers panel or, if the Layers panel is not visible, click the Window
menu, and then click Layers.

Setting Layers Panel Options
doesn’t have a lot of options for controlling the Layers panel itself;
in fact, there are only a few—changing the size of the layer row and
showing or hiding layers by type. You can choose to view the layer row
size in a small (12 pixels), medium (20 pixels), or large (32 pixels)
size, or you can select a custom size. You can choose to show or hide
thumbnails based on type, including Layers, Top Level Only, Groups, and
