Bun, am reusit stergand din header.php tot ce era legat de <div id="logo">.
Dar acum dupa cum se poate vedea meniul e putin cam scurt. As vrea sa-l lungesc pana la finalul sidebar-ului.
Cred ca codul de mai jos trebuie editat, dar nu stiu exact cum. Multumesc tuturor!

<div id="menu" class="div-as-table <?php global $st_Settings; if ( !empty( $st_Settings['stickymenu'] ) && $st_Settings['stickymenu'] == 'no' ) echo 'no-sticky-menu' ?>">
<div>
<div>
<span id="menu-select"></span>
<?php
// Menu Primary
st_menu_primary();
?>
<form action="<?php echo esc_url( home_url( '/' ) ); ?>" method="get" role="search" id="search-form-header">
<span></span>
<input
type="text"
name="s"
value=""
placeholder="<?php _e( 'Search...', 'strictthemes' ) ?>"
