## Sidebar
The option **“Gallery size”,** enables one to decide the image size using 12 grid areas. You can choose to display the gallery of images: 4/12, 5/12, 6/12, 7/12 or 8/12 of a line:
If you enable this option, a sidebar will be shown on the product page. You can choose on which side of the product page it should be shown: **“Left”** or **“Right”**. In case you don´t want it to be shown, you can choose the “Off” option in the “Sidebar position”. You can configure content for the sidebar section by adding Theme Blocks in *Products -> Product page -> Add block.* More information about how to customize the sidebar you can find [**here**](https://mpithemes.gitbook.io/shella-shopify-theme/products/product-page/theme-blocks#sidebar-on-the-product-page).
The option **“Enable sticky sidebar”** allows the sidebar to remain sticky on the product page while scrolling down the browser page. If you disable this option, there will be a blank white space on the left or right side of the product when scrolling down the browser page.
## Tabs
Here you can enable the option **“Show tabs”** if you want them to be displayed on product pages. If you do not desire to have any tab, disable the option.
Additionally, you can decide whether to show tabs **“Show tab for Description”** and **“Show tab for Reviews”** by enabling or disabling the options. Checkmark **“Scrolling to open tab”** in case you need to scroll up to the opened tab. This option works only for the vertical tabs on both desktop and mobile versions.
### Tabs type
In this section, you can select one of the options: **“Default tabs”** or **"Sheet of tabs"**.
Once you select the “Sheet of tabs" option, the Reviews, and Description blocks will be displayed without a tab, but all other tabs will be hidden using this combination.
