e.g.

• use different template for mobile/tablet devices.
• change branding/menus on your site for visitors coming from an affiliate or from a different country (GeoIP).

You simply set up "conditions" to be detected, plus the "actions" to be performed when the conditions are met. Chameleon does the rest!

Chameleon detects:

• ★ Browser (IE v6, FF, iPhone, iPad, tablet, mobile etc; using Categorizr for smart detection)
• Browser language
• Date, time, time of day
• Page type (article, category, front page etc)
• Virtuemart page types, products, cart contents, categories & coupons
• Hikashop page types, categories & specific items
• K2 page types, categories, authors & more
• User id and group, logged-in & logged-out users
• Article id, section, category & tags (J3.x)
• Component
• Site domain/sub-domain
• Page URL & referrer
• Random probability
• GeoIP detection of the guest’s city/country
• All "children" of a given menu or menu item
• Anything else you can detect with a snippet of PHP.

After it detects any of these, Chameleon can perform any of these dynamic "actions" on the current page:

• set the template/style
• unpublish/rename menu items
• unpublish plugins
• switch the "default" Joomla page (site home page)
• switch which menu item will be highlighted as "Active"
• internal or external redirection
• dynamic find-&-replace text/HTML on the page
• set metadata, page title, and add JS/CSS
• set page language
• dynamically switch VirtueMart 2.0 shopper group (and pricing structure)
• run PHP code

More examples:

• Use a different template and change some menu items depending on which "group" the user is in
• Switch off comments plugin for a certain content category
• Use a different template just for IE users
• Use a different template if your site is embedded in FaceBook
• Do A/B testing of 2 different templates, chosen randomly. Use different Google Analytics on each template, then compare the performance.
• Use different templates for site.fr & site.de
• Set up different pricing structures using VirtueMart shopper groups, then switch shopper groups based on domain name, language, time of day or country of origin
• Timed styles, templates, menu items, and more
