I just tried to add the code in my site, it works but the selection remembers the previous tag selection. I saw the reply that you have to use the cose, but how? Thank you for your help!

The code is now the following:
import wixData from ‘wix-data’ ;

const databaseName = ‘Portainnesti’ ;
const databaseField = ‘tipo’ ;

$w . onReady ( function () {

$w ( '#selectionTags1' ). onChange (( event ) => { 
    **const**  selectedTag  =  $w ( '#selectionTags1' ). value ; 
    addItemstoRepeater ( selectedTag ); 
})

});

function addItemstoRepeater ( selectedOption = []) {

**let**  dataQuery  =  wixData . query ( databaseName ); 

**if**  ( selectedOption . length  >  0 ) { 
    dataQuery  =  dataQuery . hasSome ( databaseField ,  selectedOption ); 
} 

dataQuery 
    . find () 
    . then ( results  => { 
        **const**  filtereditemsReady  =  results . items ; 
        $w ( '#repeater1' ). data  =  filtereditemsReady ; 
    })

}

$w . onReady ( function () {

$w ( '#selectionTags1' ). onChange (()=>{

let VALUE = $w ( ‘#selectionTags1’ ). value
let LENGTH = VALUE . length

    console . log ( LENGTH )

for ( var i = 0 ; i < LENGTH - 1 ; i ++) {
if ( LENGTH > 1 ) {
VALUE . shift ()

        }

else { }
}
console . log ( VALUE )

    setTimeout (()=>{ 
        $w ( '#selectionTags1' ). value  = [] 
        $w ( '#selectionTags1' ). value  =  VALUE 
    }, 1 ) 
})

});
