What you'll need
Choose Window > Layers to open the Layers panel. Notice each layer displays a thumbnail indicating the type of content on the layer — such as a T for a type layer, or a thumbnail for an image layer.
Click the JULY 1-AUGUST 31 type layer. Then, Shift-click the LOGO Ellipse layer to select all four logo layers, including PRIDE FESTIVAL and LOGO Line. Click Create a New Group at the bottom of the Layers panel, double-click the new group name, and change it to Logo. Click the arrow next to the Logo layer group to see the how the layers are now organized into a collapsible group.
Select the four type layers that include the city names (Melbourne, Sydney, Newcastle, and Brisbane). Click the Layers panel menu and choose New Group from Layers. Name the group Cities.
Click Create a New Group from the bottom of the layers panel and name it Sponsors. Shift-click Sponsor1 through Sponsor5, and then Control-click (Windows) or Command-click (macOS) to select the black rule layer. Drag the selected layers into the new group.
Make sure Kind is selected from the menu just below the Layers tab so you can filter layers by the type of content they contain. Click the image icon to filter for image layers. Shift-click to select the three paint splash image layers, and use one of the methods described in the previous steps to group the layers and name the group. Click the image icon again to turn off the filter and show all the layer types.
Choose the Move tool from the toolbar and make sure the Auto-Select option is not checked. Then click the Logo group in the Layers panel. Move the logo from one side of the poster to the center. Layer groups make it easier for you to work with multiple layers at once. For example, you can change the Opacity or set the Blend mode for all the layers in a group.
