For example, if you want to limit your excerpt to 100 words you would do this:

{exp:chopper words="100"}
   {your_content}
{/exp:chopper}

By default Chopper will strip all HTML from your excerpt. If you would like to keep some basic HTML you can use the"allow” parameter to keep specific HTML tags. For example, let’s say you want to keep <p> and <b> tags:

{exp:chopper words="100" allow="<p><b>"}
   {your_content}
{/exp:chopper}

This would strip all HTML except paragraph (<p>) and bold (<b>) tags.

Another way to limit content is by a cutoff string. This is similar to the way Wordpress’s “more” feature works. In your content you could add a specific string to indicate the spot you want the excerpt to stop. Let’s say you use “<!—END—>”. To cut the excerpt off at this location you would do this:

{exp:chopper cutoff="<!-- END -->"}
   {your_content}
{/exp:chopper}

The “cutoff” parameter can be coupled with the “words” parameter in case you forget to add the cutoff string to some of your entries. This way the excerpt will be truncated at the cutoff string, OR after X words.

You can add any string at the end of the excerpt using the “append” parameter, like this:

{exp:chopper words="100" append="..."}
   {your_content}
{/exp:chopper}

This would append “...” to the end of the excerpt.

I am not sure what all other addons this will work with right now since there are so few ready for EE3 right now.
