How do I change the states of a MS box based on user selection from a Dropdown? (When user selects from a drop down, changeState() is executed)
Example, WIX’s very own: https://www.wix.com/editorx/features (mobile site) I am assuming they are using MS box in this. 
You’d use something like
//in the onReady
$w('#myDropdown').onChange( () => {
if($w('#myDropdown').value === "string 1") {
$w('#multiStateBox').changeState("state1");
} else if($w('#myDropdown').value === "string 2") {
$w('#multiStateBox').changeState("state2");
} else {
//handle errors here.
}
});
thank you, i will test it!
