thanks it helps a lot the complete solution is to make your menu
parent menu on mouse hover should show child menu(sub menu),And on click to the parent menu tab should forward us to page associated with it
solution is
open style.css and add this
/*make the menu sub-menu items drop down on mouse hover */
ul.nav li.dropdown:hover > ul.dropdown-menu{
display: block;
margin: 0;
}
then open wp-content/themes/customizr/parts/class-header-nav_walker.php
if ( $item->is_dropdown && ( $depth === 0)) {
$item_html = str_replace( ‘<a’ , ‘<a class=”dropdown-toggle” data-toggle=”dropdown” data-target=”#”‘ , $item_html);
and remove this
data-toggle=”dropdown” data-target=”#”
now your if condition look like this
if ( $item->is_dropdown && ( $depth === 0)) {
$item_html = str_replace( ‘<a’ , ‘<a class=”dropdown-toggle”‘ , $item_html);
thank to every one
