Hi @jericson and thank you for your reply,
Yes, I don’t want the (long) list to be displayed and only a combobox which displays options based on entered value [1] and allows multiple selection. Even with +20 options, I believe it’s not nice to have all options displayed and expect the user to search for the opiton they want to select. And in our case, the options are much more.
[1]: The behaviour could be like tagging users where there are suggestions as you type and then you select one. Here, in the combobox the suggestons are based on the provided opitons and there could be multiple selection based on the min/max settings.
