WP Sticky Sidebar Pro vs Agency: 5 or 20 Domains
WP Sticky Sidebar makes a selected WordPress sidebar float as visitors move down a page, keeping navigation, menus and related content within reach. Its Sticky Sidebar Class setting identifies the sidebar element. The default selector is #secondary, though a theme may require a different one. Responsive behavior depends on the active theme, and the add-on includes multi-language support.

Pro controls and domain licenses
The Pro plan lists controls to disable the floating sidebar on desktop or mobile, add CSS styling, and exclude pages. Exclusions can cover specific pages, the front page, blog page, posts, categories, tags and archives. These settings determine where the sidebar appears and how it looks.
The Pro plan includes a license for 5 domains; the Agency plan covers 20 domains. A purchased paid plan can be used forever, with support and updates available for one year. Renewing the license adds another year of support and updates.
Selectors and placement settings
A Container Class identifies the element containing both the sidebar and main content. If the setting is blank, the script attempts to determine the container. Top and bottom margin settings adjust the sidebar's position, while a screen-width setting can prevent it from appearing below a chosen width. An option to update the floating sidebar height is described for troubleshooting cases where the sidebar loses its background color.
Installation and review
Install WP Sticky Sidebar in WordPress and open its settings. Enter the sidebar's CSS class or ID, using a dot before a class name or a hash before an ID. Add the container selector if the theme requires it, then set the margins and minimum screen width.
Save the settings and review the sidebar while scrolling on the relevant pages and screen sizes. If its behavior changes unexpectedly after an update, clear the site or browser cache, save the plugin settings, then clear the cache again. Theme inspection utilities can help identify the sidebar selector.
