Multi Select Dropdown

I am working on an app, which needs to have multiselect drop down.

So as and when we keep on adding selections to the dropdown, the size of the dropdown expands to show all the selections. And the whole layout goes for a toss.

Is there a way to have dropdown select multiple items, but only show which fits in and the size dont get changed?

Thanks & Regards,

@mixy did you find any solution for this? I am facing the same issue. @chriddyp any suggestions on how we should deal with this? Say, we have 10 drop drown options, displaying all ten in a sidebar drop down looks clumsy
