How do I limit a multiple choice question to a max of 8 choices?

Unlike the Multiple Choice Field, I'm afraid the Dropdown Field does not have the feature to limit the number of options that can be selected when The Multiple Selections option is enabled. There is a workaround that we can do with the Dropdown Field to prevent submission if more than the allowed number of selections are selected. But how would you like to consider using the Checkbox in Dropdown widget instead?

Here's how it looks like on the form.

We will wait for your response.
