# Report layout options

You can control the way your report appears on the viewer's screen using the options in the *Layout* tab of the *Theme and Layout* panel.

The *Theme and Layout* panel appears when no report components are selected. You can display this panel at any time by clicking **Theme and Layout** in the toolbar. Many of the options described here are also found in the **View** menu.
