Survey Multiple Choice Max Answer

When you build a survey, multiple choice questions now have extra settings. On the question form, in the same area where you manage the suggested answers, you can tick that an answer is required and then enter a minimum and a maximum number of answers.

• The minimum and maximum fields only appear for multiple choice questions.
• They only appear when the answer is marked as required.
• If a respondent selects fewer than the minimum or more than the maximum, Odoo shows the question's validation error message and the answer is not accepted.
• The maximum must not be smaller than the minimum, and both numbers must be zero or positive; Odoo refuses to save values that break these rules.

This works on the survey.question model and the survey question form. It does not add new menus or reports; it simply extends the existing survey question screen and the existing answer validation.
