Checkbox and multiple choice fields (AKA radio fields) are great for [online surveys](http://www.wufoo.com/gallery/templates/surveys/) because you can get feedback from a user easily by suggesting a set of common answers that they can simply choose with a click. Unfortunately, sometimes the user’s answer doesn’t fit with one of the choices you offered and it’s necessary to get them to type in one of their own. This is where offering an “other” field comes in real handy!
##”Other” Option on Multiple Choice Fields[Multiple Choice Fields](https://help.wufoo.com/articles/en_US/kb/Form-Builder/field-types/#multiple) have [a built in feature](https://help.wufoo.com/articles/en_US/kb/Form-Builder/field-settings/#allow-other) right in Wufoo’s [Form Builder](https://help.wufoo.com/articles/en_US/kb/Form-Builder/) to allow an “other” option on those fields without any additional work by you. By checking that option on, the last choice in the list of options becomes highlighted in yellow. This choice allows you to name it whatever you want, but will always accompanied by a text field which allows the user to type in their own data. If the user chooses this option and types in their own answer, this answer is what will be shown in your notifications and in the [Entry Manager](https://help.wufoo.com/articles/en_US/kb/Entry-Manager/).
##”Other” Option on Checkbox Fields
To add an “other” option on a [Checkbox field](https://help.wufoo.com/articles/en_US/kb/Form-Builder/field-types/#checkboxes) in Wufoo, you’ll need to do a bit more work. You’ll just need to use our [Rule Builder](https://help.wufoo.com/articles/en_US/kb/Rule-Builder/) and an extra Single Line text field to recreate the same effect. On your checkbox field, just label the last choice as your “other” option. Then create a [Single Line Text field](https://help.wufoo.com/articles/en_US/kb/Form-Builder/field-types/#single) right below the Checkbox field and label it appropriately.
Save your form and create a [Field Rule](https://help.wufoo.com/articles/en_US/kb/Rule-Builder/field-rules/) that applies to the “other” choice, which will show the text field when checked. This way, the text field will only be displayed if they check off that “Other” option.
It’s a very simple rule for a very simple idea!
##A Note on Reports
|The Radio Button “other” will show each option a user types in as a unique choice in a report widget.|
|The Checkbox “other” option will group all “other” choices together in report widgets.|
If you’re using the Checkbox “other” technique above and you want to build a report where you can see all the unique choices that users have entered as an “other” choice, you can build two Chart widgets. One for the Checkbox field, and one for the Single Line Text field.
