Hello, mohamed emad,
Thank you for choosing XStore as your WooCommerce WordPress theme.
To change the active icon color on the main menu, please copy and paste the following CSS code into XStore >> Theme Options >> Theme Custom CSS >> Global CSS and then clear your browser cache:
.et_b_header-menu.et_element-top-level .menu>li>a i {
color: #48ff00 !important;
}
The result should look like this: https://postimg.cc/64sdZLH6.
You can change the color code as per your requirement.
Best Regards,
8Theme’s Team
