sharethis_block
This module integrates the newer ShareThis functionality with a Drupal site.
Installation
Download using your method of choice (composer recommended) and enable the module in your site.
Implementation
Drupal 8/9
Once enabled you can visit the settings form at /admin/config/user-interface/sharethis
Drupal 7
Configuration for the D7 version happens on the block's config form.
Both version
You will need to enter your Property ID and select whether you want the sticky or inline method.
The Property ID is shown in the ShareThis interface after you've configured the buttons and selected 'Get the code'. See image below:
Once you've configured the module you can place your block where you want. The block visibility settings can be used to determine which pages the ShareThis buttons should be shown on.
If showing sticky buttons you can place the block in any region and no markup should be output. A good place for it is in the footer region. If showing the inline buttons then wherever you place the block the buttons will be shown.
Important
You must enable either the sticky buttons or the inline buttons (or both) in the ShareThis interface to see anything on your Drupal site. There is a toggle button for each type that is not immediately obvious.
