What is the code to display all wishlist items in the sidebar? Currently only last added three items are showing up. I wanted to display all items in current wishlist selection.

What should I change in this file:
vendor/magento/module-wishlist/view/frontend/templates/sidebar.phtml

You can do it by plugin or overwrite of MagentoWishlistCustomerDataWishlist. I will cover pluginize getSectionData for achieving this.

VendorName/ModuleName/etc/frontend/di.xml

        <plugin name="customer_data_wishlist" type="VendorNameModuleNamePluginWishlistCustomerDataWishlist" sortOrder="1"/>

    </type>

</config>

Clear cache.

NB: Only refresh is not enough for testing working or not. Add/Remove wishlist item then magento fire sidebar section data and load.
