Multi-select dropdown (CheckMark dropdown) VS single-select dropdown (CheckMark dropdown) VS Plain dropdowns
At Secure area, we use "Checkmark dropdown" as multi-selection dropdown. I was thinking the check was indicating to the user that it is a "multi-selection" feature. But recently, I found out sometimes, single selection also "Checkmark dropdown", sometimes single selection uses "Plain dropdown", the Pajama doc doesn't give clear guideline how to use them. Here is a summary of all the confusing part I have encountered.
- Checkmark is not a clear affordance for the user. It could be multi-selection; it also could be single selection
- Having or Not having a "close icon" is not consistent and there are two different icons
- After select multi items in the list, there is not enough space to show what is selected
- There is no guideline of how many items could be in a dropdown, it could be a lot in the future.
