Multi Dropdown big problem

Good Morning
​
When i use multiple dropdown function It does not save all the selected data but only one.

Hi integrati,
​
You need to use an array name for the multiple dropdown ending in square brackets e.g. my_dropdown[]

What Bob said, but then if you want to save that to a database you need to NOT use the brackets in the save data action and remember to do {data.jsonen:field}

Thanks now it works!
