Simply enabling this plugin will add autocomplete function to the company name field in your standard Woocommerce checkout form. 
There are currently around 2 million companies in the GLEIF database from all over the world, which are all searchable with this plugin. 
Typing in the company name field will automatically trigger a search with AJAX to the free to use GLEIF public database (<a href="https://www.gleif.org/en/meta/lei-data-terms-of-use/" rel="nofollow ugc">GLEIF LEI data terms of use</a>). 
It will then use this data to show a list of matching companies to the keywords. 
When clicking on a specific company in the list, it will hide the list and prefill the correct data to the following fields:
<ul>
<li>company name (completing the searchable field)</li>
<li>address</li>
<li>city</li>
<li>postal code</li>
<li>country</li>
</ul>
Some variables are currently editable by modifying the beginning of the plugin JS file. The variables include:
<ul>
<li>Custom field selectors for custom woocommerce implementations</li>
<li>Keyup delay when triggering the search</li>
<li>Minimum keyword length</li>
</ul>
Currently there are no shown errors in case of no search results etc. 
The idea is that the plugin is minimal and doesn’t confuse the user in case there are no matches found for the inserted company name.
