dropdown not selected, shows box

Hi,

when dropdown is not selected i try to have only “box62” visible and the rest hidden.
The choices in the dropdown work fine :slight_smile:
How can I only have “box62” visible when there is no choice?

export function dropdown1_change ( event , $w ) {
if ( event . target . value === ‘Afgekeurde vergunningsaanvraag’ ) {
$w ( ‘#tabs3’ ). show ();
$w ( ‘#tabs4’ ). hide ();
$w ( ‘#tabs5’ ). hide ();
$w ( ‘#box62’ ). hide ();
}
else if ( event . target . value === “Installatietekening(en)” ) {
$w ( ‘#tabs4’ ). show ();
$w ( ‘#tabs3’ ). hide ();
$w ( ‘#tabs5’ ). hide ();
$w ( ‘#box62’ ). hide ();
}
else if ( event . target . value === “Verlichtingsberekening” ) {
$w ( ‘#tabs5’ ). show ();
$w ( ‘#tabs3’ ). hide ();
$w ( ‘#tabs4’ ). hide ();
$w ( ‘#box62’ ). hide ();
}
else if ( event . target . value === undefined ){
$w ( ‘#box62’ ). show ();
$w ( ‘#tabs3’ ). hide ();
$w ( ‘#tabs4’ ). hide ();
$w ( ‘#tabs5’ ). hide ();
}
}
