# Configuring pre-filling of forms

You can configure a form so that when the user opens it, specified values are automatically inserted into fields or certain answers are pre-selected.

You can use pre-filling:

- To suggest the answer options that you think are preferable or most likely.

- To send auxiliary or technical parameters to [hidden fields in the form](https://yandex.ru/support/forms/en/hidden-query.md) (for example, for gathering statistics). 

You can configure pre-felling for **Short answer** and **Long answer** questions directly in the form builder. These include the following question types:
- [Short text](https://yandex.ru/support/forms/en/blocks-ref/short-text.md)​
- [Long text](https://yandex.ru/support/forms/en/blocks-ref/long-text.md)​
- [Number](https://yandex.ru/support/forms/en/blocks-ref/number.md)​
- [Phone number](https://yandex.ru/support/forms/en/blocks-ref/phone.md)​
- [TIN](https://yandex.ru/support/forms/en/blocks-ref/inn.md)​
- [Email](https://yandex.ru/support/forms/en/blocks-ref/email.md)​
- [Link](https://yandex.ru/support/forms/en/blocks-ref/link.md)​

To make sure that a question is pre-filled when the form is opened, click ![](_assets/svg/default-value.svg)</svg> **Add default value** and enter the value.

For more flexible pre-filling settings (for example, for questions with multiple answer options), send the [question ID](https://yandex.ru/support/forms/en/question-id.md) and the answer value to the form using [GET parameters in the form URL](https://yandex.ru/support/forms/en/get-params.md)
