# Make question required

To do this, you will need to add some custom code to FormJoy's in-built javascript editor. See the page above for instructions on how to access this tool. 

Then, for any question type except for multiselect checkboxes, add this code to the Javascript editor:

$("\[data-question-slug='`QUESTION_SLUG`']").prop("required", true);

Just replace `QUESTION_SLUG` above with the slug of your question - keep all of the inverted commas and brackets. See the below example to make a question with slug `text_question_2` required.
