title: Make it Direct

As Alan Cooper states：「Where there is output, let there be input」. This is the principle of direct manipulation. eg：Instead of editing content on a separate page, do it directly in context.

## In-Page Editing

A tool tip invites the user to 'Click to edit'；<br>Status 3: Once the user clicks on the title, the form elements 「Input box」, 「OK」 and 「Cancel」 appear, and the cursor is positioned in the 「input box」." src="https://gw.alipayobjects.com/zos/rmsportal/EXKwsvUkIUNkHBSsOlRi.png">

Single-Field Inline Edit

If 「readability」 is more important than 「editability」, 「click to edit」 can be used.

If the priority is given to 「readability」 and the 「editability」 of operation lines need to be highlighted at the same time, 「text link/icon edit」can be used.

Besides, when switching the edit mode in the Table, it is necessary to ensure that each column does not beat." src="https://gw.alipayobjects.com/zos/rmsportal/ukbXcTHrgPmTfHmCassD.png">

Multi-Field Inline Edit

> Note：In「Multi-Field Inline Edit」, there are huge different between the content and required field, So it is more needed to use the [「Explain What Just Happened」](../docs/spec/transition#解释刚刚发生了什么) in 「Use Transition」to eliminate this visual effects.
