Working With Multiple CSS Anchors and Popovers Inside the WordPress Loop

This article tackles the complex challenge of managing multiple CSS anchors and popovers within a WordPress loop. The core issue lies in generating unique IDs and anchor names to avoid conflicts when dynamically creating tooltips.

The process involves several key components: the Popover API for tooltip toggling, CSS Anchor Positioning for precise tooltip placement, and unique identifier generation within the WordPress loop. Each popover requires a unique ID and associated popovertarget referencing that ID. Similarly, each anchor needs a unique anchor-name for proper target association.

The WordPress loop, querying page objects using WP_Query, presents the challenge of dynamically creating these unique identifiers. The article provides a sample WP_Query and outlines the desired HTML structure for each page object, including a <details></details> element containing the popover and its associated anchor.

The CSS styling focuses on resetting default popover styles and leveraging Anchor Positioning (position-anchor, anchor() function) for precise tooltip placement relative to the anchor element. The initial CSS solution, however, fails when multiple tooltips share the same anchor name.

The solution involves generating unique IDs and anchor names using WordPress functions like get_the_id() and get_the_title(). These identifiers are incorporated into both the HTML and CSS, ensuring each popover and anchor has a unique name. The article demonstrates how to integrate get_the_id() into the HTML to create unique IDs for the <details></details> element, the popover div, and the anchor element. This dynamically generates CSS rules for each tooltip, preventing conflicts.

A simplified example illustrates the implementation of unique identifiers, demonstrating the correct association between popovers and anchors. The article also highlights the need for conditional logic to display tooltips based on specific criteria (e.g., "Experimental Feature" flag in the CMS).

Finally, the article mentions a proposed ident() function that would simplify future implementations by automatically generating unique dashed identifiers, eliminating the manual generation of unique names. Until this function is widely supported, the approach outlined in the article provides a robust solution for managing multiple popovers and anchors within a dynamic WordPress environment.
