Can it be that there is a small type error in your code above. my code give a lot of errors right now.
$w.onReady(function () {
$w('#userTypeSelectionTags').onChange(event => {
let value = event.target.value;
if(value.length){
value = value.reverse()[0];//here you keep only the value f the last selection.
$w('#$w('#TagUser').value=[value];
)//here you update the selection tags value
}
//then run the filter with the value by calling the runFilter() function
})
function runFilter(){
let filter = wixData.filter();
const userType = $w('#userTypeSelectionTags').value;
if(userType.length){
filter = filter.eq('userType', userType[0]);
}
const region = $w('#regionSelectionTags').value;
if(region.length){
filter = filter.hasSome('userType', region )
}
$w('#FAQdataset').setFilter(filter);
}})
