# Single Line Textbox

The **Single Line Textbox** field enables users to type in single-line arbitrary text. When you add this field in content type, you will see a single-line textbox on the [entry](/docs/headless-cms/about-entries) page to enter plain text only, for example, a name or an address line.

**Note:** This field does not provide any formatting options and line breaks.

This field possesses certain [properties](/docs/headless-cms/about-field-properties) that you can change at any time as per your needs. The properties that can be modified are “[Display Name](/docs/headless-cms/display-name),” “[Unique ID](/docs/headless-cms/unique-id),” “[Placeholder Value](/docs/headless-cms/placeholder-value),” “[Instruction Value](/docs/headless-cms/instruction-value),” “[Help Text](/docs/headless-cms/help-text),” “[Number of Characters](/docs/headless-cms/number-of-characters),” “[Validation (Regex)](/docs/headless-cms/validation-regex),” “[Validation Error Message](/docs/headless-cms/validation-error-message),” “[Default Value](/docs/headless-cms/default-value),” “[Mandatory](/docs/headless-cms/mandatory),” “[Multiple](/docs/headless-cms/multiple),” and “[Non-localizable](/docs/headless-cms/non-localizable).”

**Additional Resource**: Read more about [Field Visibility Rules](https://www.contentstack.com/docs/headless-cms/about-field-visibility-rules/) in our documentation where we have covered them extensively.

After adding this field in content type, you will see it on your entry page as shown below:
