I hope you get the point 
block_start=""
Optional. You can specify some text that will be added at the beginning of each block, that is, after each opening <div>.
block_end=""
Optional. You can specify some text that will be added at the end of each block, that is, before each opening </div>.
The above parameters can be used to create self-contained HTML-lists per block for example:
{exp:splitter blocks="2" delimiter="</li>" class="myclass" block_start="<ul>" block_end="</ul>"}
{exp:weblog:categories weblog="default_site" style="linear"}
<li>{category_name}</li>
{/exp:weblog:categories}
{/exp:splitter}
returns
<div class="myclass">
<ul>
<li>One</li>
<li>Two</li>
<li>Three</li>
</ul>
</div>
<div class="myclass">
<ul>
<li>Four/li>
<li>Five</li>
<li>Six</li>
</ul>
</div>
A note on pagination
If you use Splitter in combination with {exp:weblog:entries} or
{exp:comment:entries} and want to use pagination you have to place special markers
inside your {paginate}-tagpair to help Splitter identify the pagination
codeblock.
Just insert <!—pagination //—> after the opening and before the closing
{paginate}-tag. The markers will be completely removed before the page is
rendered.
Example 1:
{paginate}<!-- pagination //-->
<p>Page {current_page} of {total_pages} pages {pagination_links}</p>
<!-- pagination //-->{/paginate}
Example 2:
{paginate}<!-- pagination //-->
{if previous_page}<a href="{auto_path}">Previous Page</a> {/if}
{if next_page}<a href="{auto_path}">Next Page</a>{/if}
<!-- pagination //-->{/paginate}
