I would like to hide certain Taxonomies from search form dropdown list via a checked custom term field in Taxonomy.

I currently have the following code in View Search Filter:

<label>
[wpv-control taxonomy="attorney-practice-area" url_param="wpv-attorney-practice-area" type="select" default_label="BY PRACTICE" taxonomy_order="ASC" taxonomy_orderby="name" hide_empty="true"]
</label>

And I have a checkbox custom term field in the Practice Area taxonomy with slug "hide-from-search".

How can I hide terms that has this field checked?

Hello,

It is possible with filter hook "wpv_filter_taxonomy_frontend_search_available_terms", see below sandbox website:
Login URL: versteckter Link

1) Dashboard-> Toolset-> Settings-> Custom code:
versteckter Link
Add one item, with below codes:

add_filter( 'wpv_filter_taxonomy_frontend_search_available_terms', 'hide_terms', 10, 3 );
 
function hide_terms( $terms, $taxonomy, $view_id ) {
    $curated_terms = array();
    foreach ( $terms as $term ) {
        if (  get_term_meta( $term->term_id, 'wpcf-hide-from-search', true ) != 1) {
            $curated_terms[] = $term;
        }
    }
    return $curated_terms;
}

2) Test it in frontend:
versteckter Link

It won't display the specific term "term1" in frontend
