Hey @duy.kevin! Could you be using custom code to open the dropdowns? I do not see any interaction set to any element of the collection list, hence why fs-list-resetix = true
is not working.
I do see a snippet that seems to handle the closing, or at least the toggle of the .w--open
class
<script>
document.addEventListener('DOMContentLoaded', function () {
document.querySelectorAll('.clinic-team_pop-up-close').forEach((btn) => {
btn.addEventListener('click', function () {
const dropdown = btn.closest('.w-dropdown');
if (dropdown) {
const toggle = dropdown.querySelector('.w-dropdown-toggle');
const list = dropdown.querySelector('.w-dropdown-list');
toggle?.classList.remove('w--open');
list?.classList.remove('w--open');
}
});
});
});
</script>
Which we need to modify to the following in order for it to affect newly rendered items
<script>
window.FinsweetAttributes = window.FinsweetAttributes || [];
window.FinsweetAttributes.push([
'list',
(listInstances) => {
console.log('List Successfully loaded!');
const [listInstance] = listInstances;
listInstance.addHook('render', () => {
document.querySelectorAll('.clinic-team_pop-up-close').forEach((btn) => {
btn.addEventListener('click', function () {
const dropdown = btn.closest('.w-dropdown');
if (dropdown) {
const toggle = dropdown.querySelector('.w-dropdown-toggle');
const list = dropdown.querySelector('.w-dropdown-list');
toggle?.classList.remove('w--open');
list?.classList.remove('w--open');
}
});
});
});
},
]);
</script>
Another option to the root cause would be the use of Webflow’s native dropdown list, as I can make the dropdown work for all items if I reinitate the interaction engine with this snippet
<script>
window.FinsweetAttributes = window.FinsweetAttributes || [];
window.FinsweetAttributes.push([
'list',
(listInstances) => {
console.log('List Successfully loaded!');
const [listInstance] = listInstances;
listInstance.addHook('render', () => {
window.Webflow && window.Webflow.destroy();
window.Webflow && window.Webflow.ready();
window.Webflow && window.Webflow.require('ix2').init();
document.dispatchEvent(new Event('readystatechange'));
document.querySelectorAll('.clinic-team_pop-up-close').forEach((btn) => {
btn.addEventListener('click', function () {
const dropdown = btn.closest('.w-dropdown');
if (dropdown) {
const toggle = dropdown.querySelector('.w-dropdown-toggle');
const list = dropdown.querySelector('.w-dropdown-list');
toggle?.classList.remove('w--open');
list?.classList.remove('w--open');
}
});
});
});
},
]);
</script>
However, this will break any interaction with an initial state 
We have an Accordion Attribute in case you want to try this one out, either the JS version or the IX (with the resetix attribute) version should work.
