| In addition to the answer box placeholders, the '''Formulas question type''' provides for two other types of placeholder which are used for multiple choice questions:
| | This page has been moved to '''[[Formulas:_Multiple_choice|Formulas: Multiple choice]]''' ←''click the link'' |
| * Dropdown menu placeholder
| | </p> |
| * Radio buttons placeholder
| |
| | |
| ==Why make a FQT multiple choice question?==
| |
| | |
| Because you can use all the power of the '''Formulas''' calculation engine to build the list of choices.
| |
| | |
| ==Dropdown menu placeholder==
| |
| | |
| The syntax for this placeholder is <span style="font-family:monospace;font-size:113%;">{_n:choices:MCE}</span> where
| |
| <span style="font-family:monospace;font-size:113%;">_n</span> is the placeholder name (<span style="font-family:monospace;font-size:113%;">_0</span>, <span style="font-family:monospace;font-size:113%;">_1</span>, <span style="font-family:monospace;font-size:113%;">_2</span>, etc.) as for the answer box placeholders, <span style="font-family:monospace;font-size:113%;">choices</span> is a list of strings to appear as the menu choices and
| |
| <span style="font-family:monospace;font-size:113%;">MCE</span> must appear as is.
| |
| | |
