The default icons in Oxygen’s Toggle element are + and – for expanding and collapsing respectively. If you want to change these to > and ∨ follow the steps below.

Step 1

Add the following code snippet:

Name: Enqueue Font Awesome JS


add_action( 'wp_enqueue_scripts', 'custom_load_font_awesome' );
 * Enqueue Font Awesome.
function custom_load_font_awesome() {

    wp_enqueue_script( 'font-awesome-latest', '//', array(), null );


add_filter( 'script_loader_tag', 'add_defer_attribute', 10, 2 );
 * Filter the HTML script tag of `font-awesome` script to add `defer` attribute.
 * @param string $tag    The <script> tag for the enqueued script.
 * @param string $handle The script's registered handle.
 * @return   Filtered HTML script tag.
function add_defer_attribute( $tag, $handle ) {

    if ( 'font-awesome-latest' === $handle ) {
        $tag = str_replace( ' src', ' defer src', $tag );

    return $tag;


Step 2

Add the following CSS:

.oxy-expand-collapse-icon {
    margin-right: 0.8em;
    height: auto;

.oxy-expand-collapse-icon::before {
    background-color: transparent;
    border-radius: 0;
    content: "\f107";
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    text-decoration: inherit;
    position: static;
    font-size: 32px;

.oxy-eci-collapsed.oxy-expand-collapse-icon::before {
    content: "\f105";

.oxy-expand-collapse-icon::after {
    display: none;
    transform: none;
    position: static;
