Magento – Magento2 : Disable Pagination on certain condition from Category Page

This is how you can set custom toolbar and pager for your custom collection, below is an example shared, I am using this snippet currently.

Set Toolbar and Pager inside your phtml (your file that is to be called inside static block):

/*  Set Toolbar Pagination for Custom Loaded Collection */                              
$toolbar = Mage::getBlockSingleton('catalog/product_list')->getToolbarBlock();
$toolbar->setCollection($_productCollection);

/*  Set Pager   */
$pager = $this->getLayout()->createBlock('page/html_pager', 'custom.pager');
$pager->setAvailableLimit(array($itemsLimit=>$itemsLimit));
$pager->setCollection($_productCollection);
$toolbar->addPagerLimit('grid', 50, 50);
$toolbar->addPagerLimit('grid', 75, 75);
$toolbar->addPagerLimit('grid', 100, 100);
$toolbar->setChild('product_list_toolbar_pager', $pager);
$toolbar->setData('_current_limit', $itemsLimit);

//Set order, define $sortBy and $orderBy
$toolbar->setData('_current_grid_order', $sortBy);
$toolbar->setData('_current_grid_direction', $orderBy);

To display toolbar on top of list, use :

<?php echo $toolbar->toHtml(); ?>

And to display pager on bottom, use :

   <!-- Show Bottom Pagination Toolbar -- PAGER -->
    <div class="toolbar-bottom">
          <div class="toolbar">
            <?php echo $pager->toHtml();?>
          </div>
    </div>  

• Now you can call static block on a category page
• Then you can define your file path inside that static block
• Call your custom collection inside that file and use steps above
• And That's it :) Enjoy
