Hi, Ben

Sorry for the delay

-

We don't have a built in option to achieve this, but there is a workaround you can try.

You need to open this file: ../wp-content/plugins/wpdatatables/templates/admin/table-settings/table_settings_block.inc.php and around line 367 you'll see this:

<select class="form-control selectpicker" id="wdt-rows-per-page">   <option value="1">1</option>   <option value="5">5</option>   <option value="10">10</option>   <option value="25">25</option>   <option value="50">50</option>   <option value="100">100</option>   <option value="-1"><?php _e('All', 'wpdatatables'); ?></option>
</select>

* When searching the code, it is best to search for a phrase using CTR+F,  since our devs might add new lines of code during Updates,

so i advise to search for "Rows per page selection" , and you will find the comment right above this code : 

Then you can change the options as you need them,

 for this example, i reorder some values, i added "15", and changed "All" to "1000".

                                  <option value="1">1</option>     
                                <option value="5">5</option>     
                                 <option value="10">10</option>     
                                  <option value="15">15</option>       
                                  <option value="25">25</option>              
                             <option value="50">50</option>                     
                          <option value="100">100</option>                      
                           <option value="1000">1000</option>

        Then you will see the options look like that, in the plugin, on table's Display tab :

-

Then, open ../wp-content/plugins/wpdatatables/source/class.wpdatatable.php and around line 3737 ( or search for "aLengthMenu", and replace the values as needed, in my example like this:

$obj->dataTableParams->aLengthMenu = json_decode('[[1,5,10,15,25,50,100,1000],[1,5,10,15,25,50,100,1000]]');

And the last thing to do is to go to line 544 of the same file ( or search for "setDisplayLength", and modify it so it looks like this:

public function setDisplayLength($length) {    
    if (!in_array($length, array(1, 5, 10, 12, 15, 25, 30, 50, 100, 1000))) {     
       return false;

So, again, change the values as needed.

You may also want to add the value in 

../wp-content/plugins/wpdatatables/templates/admin/table-settings/column_settings_panel.inc.php 

around line 570, 

if you wish to add that value to possible column options (if you have a select-box filter, or selectbox editor input type, this would be the number of values displayed in those drop-downs).

Please make sure to delete cache in your browser after you apply the changes.

 It works on my Test table, and Test site;   let me know if it works for you

Thank you
