Ok, so I'll try to make this as clear as possible.
So, I work in a PASS app product offering tech company and we've encountered the following issue while building a micro interaction task for one of our UIs:
At some point, the user must use a dropdown to pick two different values that will then appear side by side under the said dropdown. A colleague of mine brought up that it seemed weird to her that we asked the user to go back to the dropdown a second time in order to add the second value. According to the wireframe bellow, here are the sequential steps to complete the task at hand:
The two selected values can then be interchanged for the landing areas are draggable.
She was claiming that using two dropdown, one for each value, would be simpler. True, but the thing is that both values need to be easilly swapped and swapping dropdowns seemed a little uncommon.
Any comments will be appreciated. Also, I first looked up for UX principles that could have resolved the mather, but I haven't found anything satisfying so if any one out there could link me with appropriate UX sources to support the argument, it would eb super nice as well!
