The HTML checkboxes plugin allows users to insert and interact with HTML-based checkboxes within Obsidian notes. Unlike standard Markdown checkboxes, these can be placed inside Markdown tables and positioned freely within a note. Even if the plugin is disabled, the checkboxes remain visible, ensuring compatibility with standard Markdown formatting. Each checkbox is assigned a unique ID for interactivity, preventing duplication issues. Users can right-click to choose alternate checkbox styles, though customization depends on the applied theme or CSS.
