 * @class
 *
 * ### Overview
 * Represents a single navigation action within `ui5-side-navigation-item`.
 * The `ui5-side-navigation-sub-item` is intended to be used inside a `ui5-side-navigation-item` only.
 *
 * ### ES6 Module Import
 *
 * `import "@ui5/webcomponents-fiori/dist/SideNavigationSubItem.js";`
 *
 * @constructor
 * @extends SideNavigationSelectableItemBase

    /**
     * Defines the tag to be displayed.
     *
     * **Note:** Tags are visible when the <code>NavigationList</code> is in expanded mode,
     * and hidden when collapsed, but they are visible in the overflow of the collapsed mode.
     *
     * **Note:** Only one `ui5-tag` is allowed. The tag should use `design="Set2"`, `hide-state-icon`,
     * and `colorScheme` values 5-10 to avoid confusion with semantic colors (1-4).
     *
     * **Note:** It is recommended to limit tag width to 64px (4rem). If tag text exceeds this,
     * use shortened forms or abbreviations (e.g., "Experimental" → "Exp").
     *
     * **Important:** The <code>ui5-tag</code> must never be interactive (i.e., <code>active</code> must not be set to <code>true</code>),
     * as this would lead to nesting of interactive elements, which is not allowed.
