e.g.
- use different template for mobile/tablet devices.
- create sophisticated web personalization: change branding/menus on your site for visitors coming from an affiliate or from a different country (GeoIP).
- restrict access to certain resources on your site for visitors matching certain criteria

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 & shopper groups
★ Flexicontent page types, categories & specific items
★ 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
★ add the current user to any group, on-the-fly
★ 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 shopper group (& pricing structure), set currency, toggle catalog mode & price display
★ 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
