Navbar expand button not working

[sahandsigm749e]

Hello all,

I have a problem with my site that I'm developing. I have bought a template, and unfortunately, the vertical navbar is not expanding. I have more than the categories displayed in the navbar, but the +Category button is not working, and I can see that chrome says void(0); at the bottom of the page. I tried contacting the template developer, but no luck, and I have no idea how to diagnose this issue. Any suggestions?

Thank you.

/**

<?php
    $_helper = $this->helper('Rokanthemes\VerticalMenu\Helper\Data');
    $_config = $_helper->getConfig('verticalmenu');
    $columnsLimit = 0;
    if($_config['general']['enable']) {
?>
<?php $_menu = $block->getVerticalMenuHtml(); ?>

<nav class="navigation verticalmenu side-verticalmenu">
	<h2 class="title-category-dropdown"><span><?php echo __('Categorias'); ?></span></h2>
    <ul class="togge-menu list-category-dropdown" style="display:none;">
        <?php echo $_menu; ?>
        <li class="expand-category-link">
        	<a href="javascript&colon;void(0);"><?php echo __('Categorias') ?></a>
        </li>
        		<?php echo $block->getLayout()->createBlock('Magento\Cms\Block\Block')->setBlockId('vertical_background_images')->toHtml();?>
	</ul>

</nav>

<script type="text/javascript">
    require([
        'jquery',
        'rokanthemes/verticalmenu'
    ], function ($) {
        $(".verticalmenu").VerticalMenu();
		$('.cms-index-index .navigation.verticalmenu .togge-menu').hide();
		$('.title-category-dropdown').click(function(event){
			$('.navigation.verticalmenu .togge-menu').slideToggle('slow');
			$(this).toggleClass('active');
		});
		$( document ).ready(function() {
			var lenghtLi = $('.cms-index-index .navigation.verticalmenu .ui-menu-item.level0').length;
			var limitItemShow = <?php echo $block->getConfig('limit_show'); ?>;
			if(lenghtLi > limitItemShow)
			{
				$('.navigation.verticalmenu .ui-menu-item.level0').each(function( index ) {
					if(index >= (limitItemShow - 1))
					{
						$(this).addClass('orther-link');
						$(this).hide();
					}
				});
				$('.navigation.verticalmenu .expand-category-link').show();
				$('.navigation.verticalmenu .expand-category-link').on( "click", function() {
					$(this).toggleClass('expanding');
					$('.navigation.verticalmenu .ui-menu-item.level0.orther-link').slideToggle('slow');
				});
			}
		});
    });

Hi @sahandsigm749e 

As within code, there are some configuration available for set limit of top nav categories.

var limitItemShow = <?php echo $block->getConfig('limit_show'); ?>;

Please check with theme configuration first and update according to your requirement. 
You can also update configuration value direct from table "core_config_data" as well.

It may help you to resolve issue.
