You can enable social like/share buttons for blog posts, pages, portfolio projects, media albums and WooCommerce products. To do so, simply drag required button(s) to wide filed on the left (fig. 1):
There is an option of ‘Share buttons appearance’ which allows to change the way people interact with social share buttons at your website. You can make them always visible (see fig. 2).
Or make them show up on hover only (fig. 3):
Please note that the share buttons will not work when using Elementor page templates (Elemenor canvas, Elementor full width). Also, share buttons will not work in a single blog post, portfolio, etc. when creating a custom template using Templates > Theme builder > Single. In such case you will have to insert the share buttons using Elementor widgets.
