Required Field Checkbox

Hello im trying to make a checkbox field as Required, just in Plumsailforms. How can i make this?

Dear @sercon,
If you want to set SharePoint field to required state, but don’t want to do it in List Settings, you can actually add a validator to a field with JS.

Just put the following code inside the JS editor (after changing FIELD_NAME to field’s internal name):

	    name: 'CheckboxValidator',
	    error: 'Checkboxes are mandatory',
	    validate: function(value) {
	        if (value == true || value.length > 0) {
	            return true;
	        return false;
