PC-DIDI Mobile Fixfooter adds a three-button mobile footer

Its job is to keep up to three mobile actions visible, such as a phone call, email, WhatsApp conversation or custom page link.

This comes up because Joomla's standard navigation and module positions do not automatically provide a fixed, mobile-only action bar. Core does cover the underlying pieces: menus, module placement, menu assignment and ordinary links can be used to build a basic version, while a Custom HTML module plus CSS can handle simple buttons. A template override or custom template code is another route when the footer needs to be integrated more closely with the design. An extension becomes relevant when that work should be exposed as administrator settings rather than written by hand. According to the listing, this module goes beyond core's basic building blocks with three independently configured buttons, per-button colours, selectable layouts, divider controls, animation settings, contact-specific actions, safe-area support and a backend preview. The listing says it targets Joomla 6.

The likely audience is a business, hotel, restaurant, taxi service, holiday rental, agency or shop that wants prominent mobile contact actions and has a design to match. A site with a conventional responsive menu, no phone or messaging workflow, or a team comfortable adding a small custom module and CSS has little reason to install it.

Before installing, check the directory entry carefully. It is listed in the modules panel section, under PC-DIDI, while the compatibility text names PC-DIDI Webdesign as the developer. The listing shows four other extensions from the developer and zero reviews. It gives the license as GPL v2 or later, but does not state whether this extension is free or paid or provide a price. It also leaves unanswered how the module behaves with specific templates, cookie or privacy requirements for external WhatsApp links, accessibility details, update policy and support arrangements. The developer says no additional system plugin is required, but the extension has not been independently tested here.
