A form page is a type of page used for information addition and entry. It ensures that users enter information according to requirements and submit it for system use or guide users in application settings.
## Design Goals
Help users clearly understand the current page tasks, quickly find and locate modification targets, easily and accurately understand the meaning and effects of form items, while simplifying the filling process, ensuring that users can complete tasks accurately, easily, and quickly.
<p>Reasonable mechanisms to ensure the consequences of operations, such as providing distributed or instant save mechanisms for complex forms; offering regret and quick fix functions like return, reset, cancel, clear, and undo for different scenario tasks.</p>

### Do & Don’t
When organizing and presenting form items on the form page, pay attention to concise expression, efficiency, and accuracy to avoid increasing the cost of user input.
The titles and prompts of form items should not use incomprehensible words or be too long, causing high comprehension costs. If uncommon words are unavoidable, use auxiliary elements like help descriptions.
When a simple and quick task needs to be completed, e.g., creating with minimal information input.
### Task Decomposition and Arrangement
Decompose large, complex tasks into multiple parts and group them by relevance to reduce user input burden. Although each part is handled individually, they are ultimately submitted together. Suitable for large, complex forms. Proper task segmentation can reduce user error rates.
Organize the information users need to fill and confirm in a linear process, using step bars to inform users of the complete process and progress. Often, users are asked to confirm the information again before the final submission, and clear feedback is provided at the end of the process. Suitable for tasks with clear linear logic.
Personal profiles, application configuration, and other settings pages are infrequently used. Generally, users will not frequently modify them after operation.
**Usage Suggestions**
Choose one setting mode per page:
> - Instant Effect Mode: Changes take effect immediately when users modify options;
> - Submission Effect Mode: Use submission effect mode when there are interdependencies among settings items.
Determine whether to group according to the number of settings items:
- The core of a form page consists of form items. It is recommended to familiarize yourself with the [basic rules of forms](/components/form/) before designing;
- Organize the information types involved in the user's current information entry tasks, and determine the components to be used according to the [Ant Design data entry rules](/docs/spec/data-entry/).
### Layout Methods
In a single form page, reasonable layout should be made according to the amount of content to balance page display and user efficiency. Form page layout can be divided into four gradients from simple to complex, and each gradient is compatible with the previous layout method.
Arrange all the information to be filled out from top to bottom in a single column within one area, guiding users to read vertically. According to [research](https://www.uxmatters.com/mt/archives/2006/07/label-placement-in-forms.php), this is the most efficient layout method for task completion.

When space is limited, form items with shorter widths and relevant content can be grouped into one line, suggesting grouping.
When there is a lot of content on a page (usually more than two screens) that can be categorized, card grouping can be used to carry it. Each card needs to include a large title.
The determination of which layout method to use is similar to the [Detail Page](/docs/spec/detail-page#%E8%AE%BE%E8%AE%A1%E5%BB%BA%E8%AE%AE), and should be sorted out from the two dimensions of information complexity and relevance. Then choose the appropriate template to quickly build the page.
