# Title Customization (Angular)

Question and page titles provide context and help organize survey content into logical sections. This example demonstrates built-in title customization options.

## Title Anatomy

Question and page titles consist of the following parts:

- Title text
- *(Optional)* Question or page number
- *(Optional)* A symbol or text that indicates a required question or page

### Title Text

To set title text for a question or page, specify the [`title`](https://surveyjs.io/form-library/documentation/api-reference/question#title) property. If you leave it unspecified, a question displays the [`name`](https://surveyjs.io/form-library/documentation/api-reference/question#name) property value as a title, while a page displays no title.

### Question Numbers

To display question numbers, enable `SurveyModel`'s [`showQuestionNumbers`](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#showQuestionNumbers) property. Questions are numbered starting with 1. If you want to start numbering with a different number or use letters instead, specify the [`questionStartIndex`](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#questionStartIndex) property. You can include desired prefixes and postfixes in the property value. In this demo, you can change the `questionStartIndex` property value at runtime using the Settings panel.

For more information on how to manage numbering within your survey, refer to the following demo: [Question Auto-Numbering](https://surveyjs.io/form-library/examples/how-to-number-pages-and-questions/).

### Required Mark

Questions that require an answer are marked with an asterisk `*`. You can use `SurveyModel`'s [`requiredMark`](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#requiredMark) property to set another symbol or specify an explanatory text string. Open the Settings panel to change the required mark in this demo.

### Title Pattern

You can arrange the question title, number, and required mark in different sequences. To do this, specify one of the [`questionTitlePattern`](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#questionTitlePattern) property values: `"numTitleRequire"`, `"numRequireTitle"`, `"numTitle"`. Use the Settings panel to see how these values affect question titles.

## Dynamic Placeholders

Panels and questions support placeholders that may be useful in titles:

- `{pageno}`\
The current page number.

- `{pagecount}`\
A total number of visible pages.

- `{correctanswers}`\
The number of correct answers in a [quiz survey](https://surveyjs.io/form-library/examples/make-quiz-javascript/).

- `{incorrectanswers}`\
The number of incorrect answers in a quiz survey.

- `{questioncount}`\
A total number of visible questions.

In this demo, page titles use the `{pageno}` and `{pagecount}` placeholders.
