This is a short and sweet autocpmplete plugin, useful for autocompleting 
words, as the post author types the contents in the wordpress content area. 
By default, “wordpress” is the only word, which is autocompleted. So after 
installing and activating the plugin, when you, as an author, start typing 
the blog contents, after adding a new post, and when when you type “wo” , 
a small autocomplete box pops up beneth, with “wordpress” written on it. 
If you want to type “wordpress”, you can click on that widget, or if you 
want to type “wolverine” , you can keep typing, ignoring the widget. 
For adding more words, go to settings=>autocomplete options 
In the top row, there is a text box and a button. Type the word you want to 
add and press the “add word” button. This text box accepts only alphanumeric inputs. 
Now the new word is added in the list. To reset the list, press the “reset” button. 
And the list now resets to the original value “wordpress” 
This plugin uses “textcompleter” Jquery plugin by “Yuku Takahashi”

This plugin is unique in that it allows you to add a Google Address Autocomplete to anything on your WordPress website. It is not made to be specific for any one e-commerce, form, LMS, or other WordPress plugin… is compatible with them all!
Address Autocomplete is my favorite feature on any e-commerce site or any time I need to fill out a form on a website. Originally built for our other plugin, <a href="https://wordpress.org/plugins/sunshine-photo-cart/" rel="ugc">Sunshine Photo Cart</a>, I realized I could make this available to work for anything.
<h3>How it works</h3>
By using CSS selectors (don’t worry non-tech person, it is easier than you think and a <a href="https://wpsunshine.com/documentation/finding-your-css-selectors/?utm_source=wordpress.org&utm_medium=link&utm_campaign=address-autocomplete-readme" rel="nofollow ugc">simple help article and video is available</a>!), you can add Address Autocomplete to Anything! Provide a selector for which input field on your page you want to trigger the address autocomplete when a user types, and then the CSS selectors to target for the address data.
<h3>What you need</h3>
You only need to <a href="https://wpsunshine.com/documentation/google-maps-api-key/?utm_source=wordpress.org&utm_medium=link&utm_campaign=address-autocomplete-readme" rel="nofollow ugc">get a Google Maps API key</a>. Although billing info is required, most sites will never be charged as the free limit is quite high.
