An example for a drop down menu with a warning:
...
Use when:
The options list is small-medium in size , and space is constrained.
Up to 10-15 items: use regular multi-select dropdown
15-50
Use the searchable type when there are more than 15 item and the user knows what he’s looking for (and aware, to some extent, how it's named in the option list)
: use searchable multi-select dropdown
Don’t use when:
The list has less than 7 options and the user needs to see them all at once. Use radio buttons or Check box instead.
The user needs to enter a value which is not in the list. Use a combo box instead.
The list has more than 50 (TBD) items, use is large. Use Dual List Selector or List instead.
General:
Only a list with over 8 items should show a scrollbar.
Keep the text values as short as possible because the list uses single lines only.
The option list should adapt its length to the longest entry by default, but values that are too long may be truncated, having a tooltip displaying their full text (not recommended) - There is no horizontal scrolling in the option list.
Place options that represent All or None at the beginning of the list, regardless of the sort order of the remaining items.
Do not allow the control to auto-adjust based on the selection.
If there’s no label or if the label is not indicative enough, the selected item type should be indicated within the dropdown:
