VP Iframe Assistant

VP Iframe Assistant adds a floating button to your website. When clicked, it opens a chat-style side panel (full screen on mobile) that loads any conversational assistant embedded through an iframe.

It is provider-agnostic: you just paste the iframe URL of the assistant you want to embed. It works with any service that offers an embeddable iframe — for example, a Q-soft (e-salus) appointment assistant, a support chatbot, a booking widget, an AI assistant, etc.

The plugin itself does not connect to or send any data to external servers. The iframe is loaded directly in the visitor’s browser, against the URL configured by the site administrator.

Transparency: this plugin was developed with AI assistance (Claude) and was reviewed and audited manually by the Visual Publinet team, including a security and privacy review. It has no external dependencies and no API keys.

Features

• Fixed floating button, configurable (text, icon, position, colors).
• Side panel viewer, full screen on mobile.
• Lazy loading of the iframe (does not affect page speed).
• Full settings panel with a live preview of the button and viewer.
• Optional, configurable privacy notice in the viewer footer.
• Open the assistant from any other element via the vpifa-open CSS class or a JavaScript API.
• Open the assistant from selected WordPress menu items, chosen right from the settings.
• Minimal iframe permissions and a strict referrer policy by default.
• Accessible (ARIA roles, focus management, close with the Esc key).
• Available in English and Spanish (translation-ready, with a bundled es_ES translation).

Default configuration

• Iframe URL: empty (must be set under Settings → VP Iframe Assistant). The button is not shown until a URL is provided.
• Button text: “Open assistant” (“Abrir asistente” in Spanish).

Opening the assistant from other buttons

In addition to the floating button, you can open the assistant from any element on the website by adding the CSS class vpifa-open (or the data-vpifa-open attribute):

• HTML: <a href="#" class="vpifa-open">Open assistant</a>
• Menus (Appearance > Menus): enable “CSS Classes” in Screen Options and type vpifa-open.
• Gutenberg / Elementor buttons: “Additional CSS classes” field > vpifa-open.

You can also pick existing menu items directly from the plugin settings (“Open from a menu item”): tick the menu entries that should open the assistant and the plugin adds the trigger for you, no CSS class needed.

It can also be opened with JavaScript: window.vpifaCita.open() (and .close() / .toggle()).
